to lower its electrostatic self-energy, which consequently leads to an
increase in DNA ejection. By fitting our theory to available
experimental data, the strength of DNA-DNA short range attraction
energies, mediated by Mg+2, is found to be -.004 kBT per nucleotide
base. This and other fitted parameters agree well with known values
from other experiments and computer simulations. The parameters
are also in agreement qualitatively with values for tri- and tetra-valent
counterions.
Application of the Statistical Moment Method to Thermodynamic
and Mechanical Properties and EXAFS Cumulants of Bulk
Materials and thin Films: Metals, Oxide Materials and
Semiconductor
Vu Van Hung
Hanoi National University of Education, 136 Xuan Thuy Str., Hanoi,
Vietnam
The systems considered at high temperatures and high pressures
require the allowance for anharmonic effects which are very essential
in these regions. The anharmonic effects of lattice vibrations and high
pressures and size on the thermodynamic and mechanical properties
and EXAFS cumulants of the bulk materials and thin films (like as
metals, oxide materials and semiconductors) have also been studied
by the statistical moment method (SMM). In the present report, we
use the finite- temperature moment expansion technique to derive
the free energies and equation of states of bulk materials and thin
films. The thermodynamic quantities, elastic moduli and elastic
constants and EXAFS cumulants are determined. We discusss the
temperature, pressure and size dependences of thermodynamic and
elastic properties of bulk materials and thin films and compare the
SMM calculations with those of the experimental results and other
theories.

Topological Insulator: a Novel Quantum State of Matter
Tran Minh Tien
Institute of Physics, VAST
In this talk we will present the recent developments of topological
insulator, a novel quantum state of matter. The topological insulators
like the conventional insulators have the energy gap in bulk, but their
surface or edge states are gapless. We will focus on the physical
properties of a magnetic impurity embedded on the surface of a
topological insulator. It is shown that the physical properties are quite
different from the counterpart of the conventional surface of gapless
states. We will also discuss on the Kondo topological insulator.

The problem of inhibiting viral DNA ejection from bacteriophages by
multivalent counterions, specifically Mg+2 counterions, is studied.
Experimentally, it is known that MgSO4 salt has a strong and nonmonotonic effect on the amount of DNA ejected. There exists an
optimal concentration at which the minimum amount of DNA is
ejected from the virus. At lower or higher concentrations, more DNA
is ejected from the capsid. We propose that this phenomenon is the
result of DNA overcharging by Mg+2 multivalent counterions. As
Mg+2 concentration increases from zero, the net charge of DNA
changes from negative to positive. The optimal inhibition corresponds
to the Mg+2 concentration where DNA is neutral. At lower/higher
concentrations, DNA genome is charged. It prefers to be in solution
A nonlinear tunneling and transport dynamics of Bose-Einstein
condensate (BEC) is discussed. The main attention is paid to
Josephson oscillations, macroscopic quantum self-trapping, and
controlled adiabatic transport. The discussion is focused to nonlinear
effects which usually break the transport. To overcome this trouble,
the novel effective and universal transport protocols are developed
on the base of the Landau-Zener and Rosen-Zener schemes. They
are robust in a wide range of the BEC interaction and turn the
nonlinearity from the detrimental to useful factor. The perspectives of
using BEC transport for generation of geometric phases and other
applications are discussed.

In my talk I present a new approach to the quantization problem of
classical mechanical systems with compact phase spaces. This
approach generalizes quasi classical method of Maslov and Karasev
where states of the quantized system are presented by weighted
lagrangian cycles in the classical phase space. In contrast with the
classical Maslov method we can avoid the introduction of certain
correction classes (f.e. the celebrated Maslov class). At the same
time our new approach exploits the procedure which was addresed to
a mirror symmetry problem. So it is reasonable to expect that the
geometric construction can be modified such that it will work.

The formation of a hybridization state of Wannier Mott exciton and
Frenkel exciton in different hetero-structure configurations involving
quantum dots has been investigated. The hybrid excitons exist at the
interfaces of the semiconductors quantum dots and the organic
medium, having unique properties and a large optical non-linearity.
The coupling at resonance is very strong and tunable by the
parameters of the systems (dot radius, dot-dot distance, generation
of the organic dendrites and the materials of the system etc).
Different semiconductor quantum dot-organic material combination
systems, such as a semiconductor quantum dot lattice embedded in
an organic host, a semiconductor quantum dot at the center of an
organic dendrite, a semiconductor quantum dot coated by an organic
shell, have been considered . The formation and the properties of the
organic-semiconductor hybrid excitons have been modulated by
electric and magnetic fields. The hybrid excitons are as sensitive to
external perturbation as Wannier-Mott excitons. We investigate the
effect of mutual presence of electric and magnetic fields on the hybrid
exciton of the isolated semiconductor quantum dot such as CdSe
(core) clothed by an organic or glass coating for two configuration of
fields when the electric and magnetic fields are parallel and
orthogonal. The fields affect the eigenfunctions (by a Stark -effect
distortion and by the magnetic field induced distortion) and the
Frenkel-Wannier coupling term. Upon the application of the magnetic

and electric fields the coupling term between the two kinds of
excitons increases. The most important feature of this system is by
adjusting the magnetic and electric fields, one can tune the
resonance between the two kinds of excitons to get different regions
of mixing to obtain the expected high non-linearity.

the CP violation of asymmetry depends on the weak phase and
strong phase of form factors. By including the scalar and vector
mesons into the chiral Lagrangian, we compute the form factors of
the hadronic system at the one loop correction. The direct CP

During the past 25 years, the GW method [1] has been successfully
used to compute electronic quasi-particle excitation spectra of a
variety of materials. It is however a computationally intensive
technique, as it involves summations over occupied and empty
electronic states, to evaluate both the Green function (G) and the
dielectric matrix (DM) entering the expression of the screened
Coulomb interaction (W). Recent developments have shown that
eigenpotentials of DMs can be efficiently calculated without any
explicit evaluation of empty states [2]. In this work, we will present a
computationally efficient approach to the calculations of GW spectra
by combining a representation of DMs in terms of its eigenpotentials
[3] and a recently developed iterative algorithm [4]. As a
demonstration of the efficiency of the method, we will present
calculations of the vertical ionization potentials of several systems. [1]

In this report, we use Monte Carlo simulation to study the magnetic
properties of nanoparticle-chains which are formed from individual
nanoparticles with identical size under combined influence between
dipolar interaction and magnetic field in the presence of particles’
uniaxial anisotropy. In the agreement with the literatures, the uniaxial
anisotropy with easy axis along the chain length is found. Basing on
hysteresis loops we calculate magnetic responses along the chain
length and in perpendicular direction. We found that those are
sensitive to synthesizing field as well as particles’ uniaxial anisotropy.
We also explore the possibilities of anti-ferromagnetic intra-chains
found in experiment by considering the orientation distribution of
magnetic moments after the magnetic relaxation process. Contrary to
distinct particle systems in literatures, the anti-ferromagnetic ordering
is favored at high temperature. Finally, we investigate the influence of
temperature on the magneto-resistance of self-assembled
nanochains

Phan Thi Hong Ngat
Computational Materials Science Laboratory, Faculty of Physics,
Hanoi University of Science, Vietnam
In this paper, ab initio calculation on the BaTiO3 quantum-rods was
carried out in the framework of density functional theory (DFT) using
local density approximation (LDA). While both LDA functional and
gradient corrected versions underestimated the optical gap of the
bulk BaTiO3, the LDA ones resulted in the better fit with experimental
data. The shape ratio of the rods varied from 1:10 to 1:1 for single
unit cell cross-section rods (SURs) and from 2:10 to 2:2 for double
unit cell cross-section rods (DURs). Each rod ended at BaO plane or
TiO2 plane. One of the most interesting observations obtained from
the calculation was the structural-phase transition along the rods
which has been addressed as the smeared phase transition in
literatures. Besides, the mean values of c:a which were averaged
over unit cells of each rod showed the stability of the tetragonal
phase for BaO ended SURs (type A1) with length above 1.6 nm. For
BaO ended DURs (type A2), the tetragonal phase was shown to be
stable at length above 1.3 nm. These two lengths can be considered
as the cubic-tetragonal transition lengths. The structural-phase
transition did not occur for the TiO2 ended SURs (type B1) and
DURs (type B2) at any length up to 3.2 nm. Reduction of the
interaction energy between surface charges stimulates a formulation
of 180o domain wall at the middle of each rod of all types.
Additionally, there are an anomalous flipping of the electric dipoles at
the ends of the A2 rods

It has been observed that distribution of stock market indexes are
convergent from Boltzmann distribution to Gaussian asymptotic one.
We proposed a new and simple dynamic model to describle this
convergence by time parameter, with the introduction of the
relaxation time concept for a market. The result showed that our
model fits well with the financial market data. Relaxation time value is
little in the stable period, and big in the crisis period of the market.

We presented a theoretical study of the distribution of twodimensional electron gas (2DEG) along the quantization direction in
an AlGaN/GaN modulation-doped heterostructure (MDHS). All
confining sources, such as potential barrier, interface polarization
charges, ionized donors, and 2DEG are properly taken into account
within the realistic model of finitely-high barrier. We showed that the
peak of electron wave function (2DEG peak) is located in a channel
region near the interface plane and depends strongly on the
confining sources. Irrespective of the model of finitely- or infinitelyhigh potential barrier, the 2DEG peak is lifted with a rise of the sheet
polarization charges density and lowered with a rise of the 2DEG
density. Since the key mechanisms limiting lateral transport in MDHS
are alloy disorder and surface roughness scatterings that are very
sensitive to the 2DEG distribution near the interface, the 2DEG
mobility is found to depend strongly on the charge density of
confining sources, inclusive of donors despite negligibly weak
scattering from correlated donors.

The geometric structure, electronic structure and spin transition of

[Fe(abpt)2(NCSe)2] (2), and [Fe(abpt)2(tcm)2] (3) with abpt = 4amino-3,5-bis(pyridin-2-yl)-1,2,4-triazole and tcm– = [C(CN)]– =
tricyanomethanide anion have been studied based on Densityfunctional theory. All results presented in this study were obtained by
using the exchange correlation PBE functional. The effective core
potential Dolg-Wedig-Stoll-Preuss were used to describe the
interaction between the core and valance electrons. For better
accuracy, the hexadecapolar expansion scheme is adopted for
resolving the charge density and Coulombic potential. Both geometric
structures corresponding to the high-spin and low-spin states of
these molecules obtained from our calculations are in good
agreement with available experimental data. Our calculated energy
difference between the low and high spin states is 0.14, 0.18, and
0.20 eV for (1), (2), and (3), respectively. Also, we succeed in
determining the spin transition state of these molecules by using the
Linear-Synchronous-Transit method.

The LLG is equatuion is a well known approach for the damping
mechanism of magnetization, In this work, by using Many Body
Formalism we calculate the correction to the LLG equation due to the
scattering of electrons with magnetization. The correction was
obtained by evaluating the back reaction of the spin torque. The
corrections are obtained for both time dependent and time
independent mgantization distribution. Our results are different from
the results reported previously by using the spin projection method
together with applying the Omh's law where such approach is in fact
unjustisfied.

The influence of the local-field correction on the strong atom-field
coupling regime are investigated using the real-cavity model. The
atom is positioned at the center of a multilayer sphere. Three types of
mirrors are considered: perfectly reflecting, Lorentz band gap, and
Bragg-distributed ones, with special emphasis on experimental
practicability. In particular, the influence of the local field on the
spectral resonance lines, the Rabi oscillation frequency and decay
rate, and the condition indicating the occurrence of the strongcoupling regime are studied in detail. It is shown that the local-field
correction gives rise to a structureless plateau in the density of states
of the electromagnetic field. The level of the plateau rises with
increasing material density and/or absorption, which may eventually
destroy the strong-coupling regime. The effect of the local field is
especially pronounced at high-material densities due to direct energy
transfer from the guest atom to the medium. At lower material density
and/or absorption, variation of the material density does not seem to

Study of thermodynamic properties of highly excited (hot) nuclei has
been a topic of much interest in nuclear physics. In this talk, two
theoretical microscopic approaches, which have recently developed
in Refs. [1, 2], will be presented. These approaches are derived
based on the solutions of the Bardeen-Cooper-Schrieffer (BCS)
theory and the self-consistent quasiparticle random-phase
approximation (SCQRPA) [3] in combination with the Lipkin-Nogami
particle-number projection at zero temperature embedded into two
principal ensembles, namely the canonical ensemble (CE) and
microcanonical ensemble (MCE). The results obtained agree well
with the recent data extracted from experimental level densities by

the general analytic expression for optical absorption power. We also
obtain an EPR condition as a function of the photon energy and
doped concentration of donor and acceptor impurities. We discuss
anomalous behaviors of the EPR effect such as the splitting of EPR

Nanowires grown on GaAs semiconductor substrate have many
interesting properties such as direct bandgap, controllable band
gaps, quantum confined laterally…they play very important roles in
nanoelectronics. The nanowires are often grown by different methods
such as Vapor Liquid Solid (VLS), Chemical Vapor Deposition (CVD),
Laser Ablation Catalytic Growth (LCG), Fluid Liquid Solid (FLS),
Solution Liquid Solid (SLS), Oxide Assisted Growth (OAG), and
Molecular Beam Epitaxy (MBE)… Among synthesis methods, the
VLS method is a simple, popular, cheap method. So far although
many scientific efforts achieved over more 40 years, but many
aspects of VLS method are still not yet clearly understood, for
example, the influences of technological conditions, sized effects, the
diffusion effect of Au catalyst atoms, nanowires seed formation…
This paper reports some our experimental results of synthesis of
GaAs semiconductor nanowires, and also about an abnormal
phenomena of the reverse -VLS concerning the nanowires growth,

structural properties and the effect of Au catalyst metal on the

considering any higher order terms or any symmetry breaking terms
by hand, we obtained tiny deviations of lepton mixing angles from
their tri-bimaximal values. In addition, by a reasonable choice of
model parameters compatible with low-energy data, such RG effects
lead to non-zero lepton asymmetries from the decays of right-handed

The acoustomagnetoelectric effect in a rectangular quantum wire
with an infinite potential in the presence of an external magnetic field
is investigated by using Boltzmann kinetic equation for an acoustic
wave whose wavelength λ = 2π/q is smaller than the mean free path l
of the electrons and hypersound in the region ql >> 1, (where q is the
acoustic wave number). The analytic expression for the
acoustomagnetoelectric current I is calculated in the case: relaxation
time of momentum τ is constant approximation and non-degenerate
electron gas. The dependence of the expression for the
acoustomagnetoelectric current I on the acoustic wave numbers q
and on the parameters of the rectangular quantum wires is obtained.
Numerical calculations have been done and result is analysed for

is also compared with the result of the experiment in the normal bulk

the frequency of the external strong electromagnetic wave
(electromagnetic wave = EMW), the temperature T of the system,
and the cyclotron frequency for case of an external magnetic field is
obtained. The analytic expressions are numerically evaluated,
plotted, and discussed for a specific CSL GaAs-Al0.3Ga0.7As. The
computations show that the NAC in CSL is much more greater than

The electrophonon resonances (EPR) and optical detected electron
energy spectrum (ODEES) in rectangular quantum wires (RQWs) are
investigated by using the quantum kinetic equation (QKE) for
electrons to obtain the general analytic expression for optical
absorption coefficient. We also obtain ODEES conditions as
functions of the photon energy. In particular, due to the appearance
of peaks in absorption spectrum satisfying the condition of electronphonon resonance we obtain a relation between photon energy,
distance of the two peaks, and electron subbands in the RQWs. The
importance of the result is that the splitting of peaks for incident
photon energy can be used to detect electron energy spectrum in the
special RQW. The obtained ODEES show that they do not depend
on the temperature.

due to their linear dispersion law, this equivalency is quite good for

Scattering as a source of sub- nanosecond optical pulses
Chu Van Bien

We present a computer numerical mode (virtual sub- nanosecond
laser) utilizing intra-cavity stimulated Raman scattering. The goal of
this work is to shorten laser output pulses (for which the highly
nonlinear fredquency conversion process – stimulated Raman
scattering – is used) and to obtain high efficency (which is enhanced
by placing a Raman- active crystal inside the cavity where the
fundamental laser frequency intensity is maximal). The following
laser components were modeled: a diode- pumped soild- state laser
active medium (a crystal of the Nd3+: YLF type), a closed cavity for a
wave on its fundamental frequency with a Q- switching element and
an internal sub- frequency. The model components are: a numerical
integrator of a set of three rate equations (for an inverse population
of the laser medium and for the number of fundamental and Stokes
frequency phontons), random number sources for radiation seeding,
and an interactive data input interface and graphic output. A wide
range of parameters was investigated and output pulses as short as
0.8 ns were found. The optimal conditions for the maximal peak
power of Stokes pulses were determined and the conditions for
generating pulse trains for burst laser machining were identified.

Using the molecular dynamics method within Born-Oppenheimer
approximation implemented in the GAUSSIAN, we simulate the
imino-amino tautomerism of cytosine, one of four bases of the DNA
molecule. We have also calculated high-order harmonics, emitted
from cytosine while interacting with ultra-short 800 nm laser pulses
along the chemical reaction path of the tautomerism by the strongfield approximation using Lewenstein model. We identify that the
calculated high-order harmonic spectra have intensity peaks nearby
the stable states (imino and amino) as well as the transition state.
This finding may be a useful tool for tracking the DNA tautomerism,
one of reasons for gene mutation.

In this work, we present the application of Drude - Lorentz theory in
analyzing experimental spectroscopic ellipsometry data to determine
the resistivity of ultra-thin titanium nitride films. The films were
deposited on silicon substrates at 350 oC using atomic layer
deposition technique. The growth of the films was in situ monitored
by spectroscopic ellipsometry from which the complex dielectric
functions of the layers were determined. The measured dielectric
functions were parameterized by employing the Drude - Lorentz
model in combination with the COMPLETEEASE modeling software.
The resistivity of titanium nitride was extracted from the
parameterization. A resistivity of 160 microohm-cm was obtained for
a 10 nm thick film. The resistivity slightly decreased with increasing
film thickness and reached values of 150 and 145 microohm-cm for
films with thicknesses of 15 and 20 nm, respectively.
P-36. Femtosecond Supercontinua Generated in Birefringent Photonic
Crystal Fibers
LECONG Nhan
University of Sai Gon
Supercontinua (SC) generated in photonic crystal fibers (PCF) have
emerged in the past years as attractive light sources for optical
coherence tomography [1], non-linear microscopy [2,3] and ultrafast
spectroscopy [4,5]...For the latter application, we have developed a
pump-probe experiment based on sub-cm birefringent PCF [6]. We
report here on new findings, obtained by studying the spectrotemporal properties of the SC as a function of fiber length. We show
that the SC, generated in the core of the birefringent PCF, has a
linear polarization and the spectrum extends on the UV (340 nm) can
be obtained for the injection laser pulses in the glass interstitials. The
birefringent PCF in this work was produced at the XLIM laboratory
(Limoges, France) by using the standard stack-and-draw method.
This fiber has an asymmetric core which induces strong
birefringence, thus the light output in this core has a linear
polarisation. The cladding is composed by a periodic micro structure
made of air holes and silica. Guiding takes place in the core, but is

also possible in the cladding interstitials. Light propagation
undergoes the material dispersion and guiding dispersion. This PCF
has four zero-dispersion wavelength (ZDW) at 866, 827, 764 and 757
nm respectively for four different modes LP01y, LP01x, LP11y and
LP11x. Femtosecond SC generation in the PCF only requires laser
pulses of a few nJ for injection. Our laser source is a Ti:Al2O3
oscillator. Thanks to the micro structure, the light is confined in a
small diameter of silica, the abnormal dispersion favors the soliton
propagation. Those enhance the non linear phenomena like: self
phase modulation, cross phase modulation, four wave mixing,
Raman stimulation, soliton propagation…which are responsible for
the SC generation. By studying the SC properties generated in one
of the interstices and in the core we have found that the SC
generated in the interstice extends more in the blue than the SC
generated in the core. The larger spectral coverage is most probably
due to the smaller diameter of the cladding structures, which afford
for a shorter zero dispersion wavelength.

A simulation study was carried out for amorphous SiO2 at
temperature of 300 K under pressure from 0 to 60 GPa. The solubility
of noble gasses into the SiO2 glass was computed assuming that
only large non-overlapping simplexes can contain a noble atom. The
calculation shows a good agreement with experimental data of noble
solution in silica glass. The local structure of silica is analyzed
through the scattering structure factor S(q) and simplex statistic. We
found that the first sharp diffraction peak S(q) shifts to larger value q
with increasing the density of silica. This relates to the change in
amount of large simplexes. The densification mechanism of silica is
also analyzed and discussed here.
Considering the nine-dimensional MICZ-Kepler problem, we establish
the Runge-Lenz vector that describes the hidden symmetry of the
problem. We also build the group of the hidden symmetry SO(10),
which Casimir operators are established that allow us to investigate
the problem by the algebraic method.

suitable values of the squeezed field parameters we found a nearly

allows the propagation of nearly dispersionless and distortionless
pulses. Furthermore, we have found that the probe absorption can be

The ability of proteins to aggregate and form toxic amyloid fibrils has
been associated with a range of diseases including BSE (or madcow), Alzheimer’s and Parkinson’s Diseases. In this study, we
investigate the aggregation mechanism of short peptides by using
the tube model for hydrophobic-polar (HP) sequences. Extensive
Monte Carlo simulations are carried out with the use of parallel
tempering technique. Our results show that the conversion from
disordered aggregates to cross-link beta-structures depends on the
HP sequence and the number of peptides. Comparison to the
homopolymer case shows that the HP sequence enhances the
propensity of forming fibrillar structures leading to more ordered
alignment of peptides.

We introduce and study the behavior of a tethered membrane of nonzero thickness embedded in three dimensions subject to an effective
self-attraction induced by hydrophobicity arising from the tendency to
minimize the area exposed to a solvent. The phase behavior and the
nature of the folded conformations are found to be quite distinct in
the small and large solvent size regimes. We demonstrate
spontaneous symmetry-breaking with the membrane folding along a
preferential axis, when the solvent molecules are small compared to
the membrane thickness. For large solvent molecule size, a local
crinkling mechanism effectively shields the membrane from the
solvent, even in a relatively flat conformation.

carrier density, layer thickness and magnetic field. We include the
many-body effects using the three-sum-rule version of the selfconsistent approach of Singwi, Tosi, Landand and Sjolander. We
discuss the multiple-scattering effects and critical density of the
metal–insulator transition.

We investigate the Coulomb drag resistivity in dilute bilayer 2D hole
systems including local field effects in the framework of Fermi liquid
theory. We study the dependence of Coulomb drag resistivity on the
carrier density, temperature, quantum well width and inter-layer
distance using the RPA and Hubbard approximation. In special case
our results reduce to those obtained by Hwang and coworkers (
Phys. Rev. Lett. 90, 086801 (2003)). Our results and future
experiments will give information about the many-body effects in twodimensional systems.

The absorption coefficient of a weak electromagnetic wave by
confined electrons in the presence of laser radiation in doped
superlattices is calculated by using the quantum kinetic equation for
electrons. The analytic expressions of the absorption coefficient of a
weak electromagnetic wave in the presence of laser radiation field for
the case of electron – optical phonon scattering are obtained. The
dependence of the absorption coefficient on the intensity and
frequency of the external laser radiation, the intensity and frequency
of the weak electromagnetic wave, the temperature T of the system
are analyzed. The results are numerically calculated, plotted, and
discussed for n-GaAs/p-GaAs doped superlattices. The appearance
of a laser radiation causes surprising changes in the absorption
coefficient. All the results are compared with those for the normal
bulk semiconductors to show the difference. Keywords: Absorption

Based on the quantum kinetic equation for the confined phonons, the
amplification of confined sound (confined acoustic phonons) by
absorption of a laser radiation in a cylindrical quantum wire with an
infinite potential is studied for the case of monophoton absorption
process and the case of multiphoton absorption process. Analytical
expressions and conditions for the rate of confined acoustic phonons
are obtained. Differences between the two cases of monophoton and
multiphoton absorption process are discussed; numerical
computations and plots are carried out for a GaAs/GaAsAl quantum
wire. The results are compared with bulk semiconductors and

Abstract. The influences of confined phonons on the nonlinear
absorption coefficient (NAC) of a strong electronmagnetic wave
(EMW) by confined electrons in cylindrical quantum wires with the
parabolic hole is theoretically studied using the quantum transport
equation of elctrons. The dependence of the NAC on the radius of
quantum wires (R), the amplitude ( E0) of external strong EMW, the
temperature (T) and the frequency Ω of external strong EMW of the
system in case of the confined phonons is obtained. Two cases for
the absorption: close to the absorption threshold and far away from
the absorption threshold are considered. The formula of the NAC
contains the quantum numbers k, m characterizing confined phonons
and is easy to come back to the case of unconfined phonons when k,
m reaches to zero and the linear absorption when E0 reaches to
zero. The analytic expressions of the NAC are numerically evaluated,
plotted and discussed for a specific case of the GaAs/GaAsAl
quantum wire.The computations show that the value of the NAC in
the case of confined phonons strongly depends on k, m. The
spectrums of the NAC are very different from the linear absorption.

The half-filled isotropic degenerate two-band Hubbard model is
studied within coherent potential approximation. The model is
characterized by an Ising-type Hund’s exchange coupling, intra- and
inter-orbital Coulomb parameters. We found that the presence of

inter-orbital interaction reduces the Mott-Hubbard critical value UC
When the Hund’s exchange coupling is large enough we found a
metallic region in the insulating domain. We reveal that the system
can have two distinct critical values for Mott-Hubbard transitions.

Loi Street, Hue City, Vietnam
For roughness-dominated intersubband absorption in quantum wells,
the optical characteristics depend on roughness parameters of the
heterointerface (roughness amplitude and correlation length).
Following the earlier belief in the literature, a single-valued estimation
of them from measurement of these characteristics is impossible. On
the contrary, in our report we present an attempt at providing a
possibility for single-valued deduction of the roughness parameters
from optical data. For this purpose, we introduce the lineshape
characteristics that are independent of roughness amplitude, so
being a function of correlation length only. As a typical example, we
examine the ratio between two different absorption-peak heights.
Thus, we may propose an efficient method for individual estimation of
the roughness parameters from optical data. Instead of the normal
simultaneous fitting of both parameters to the functional dependence
of the absorption-peak height at many experimental points, we
perform a two-step fitting of (i) correlation length to the peak height
ratio at one point, and then (ii) roughness amplitude to the peak
height at one point.

We consider a model of III-V diluted magnetic semiconductors where
both of the exchange interaction between carrier and impurity spins,
and the direct exchange interaction betwwen magnetic impurities are
taken into account. The magnetization as a function of temperature
for a wide range of model parameters is calculated and disscused.

The coherent potential approximation and mean field approximation
are used to calculate the free energy of the coupled carrier –
localized spin system in III-V diluted magnetic semiconductors. Thus
the magnetic transition temperature Tc can be determined and its
dependence on important model parameters. We show that the
strong antiferromagnetic superexchange interaction between nearest
neighbor sites considerably reduces the Curie temperature.

by using a set of quantum transport equations for the phonons.
Dispersions of the resonant phonon frequency and the threshold
amplitude of the field for parametric amplification of the acoustic
phonons are obtained. If they are obtained, then they are also
estimated for realistic semiconductor models

Abstract: A new procedure for calculation and analysis of physical
parameters of real atomic vibration of fcc crystals doped by atoms of
the other crystals has been developed using anharmonic effective
potential. Analytical expressions for dispersion relation separating
acoustic and optical branches; forbidden zone; effective force
constant; Debye frequency; phase shift and amplitude of real
vibration of atomic chain containing doping atom have been derived.
They contain Morse potential parameters for doping crystal

other crystals, where the results for Cu doped by Ni agree well with
fundamental properties of these quantities and with experimental
values extracted from measured Morse parameters.

Faculty of Physics, Hanoi National University of Education
In this article, unlike previous studies, we study the full quantum
entanglement dynamics problems of the independent qubit-cavity
system while under the influence of three physical mechanisms of the
decoherence: the relaxation of excited electrons, the pure dephasing
of coherent oscillations of electron population at two energy levels
and the photon leakage. The results we obtained indicate that phase
flip mechanism, while not losing the energy of the system but to lose
information, so this mechanism is an important that not be ignored.
Speed decay of the quantum entanglement system depends on the
constant interaction with the environment. Quantum entanglement of
the independent qubit-cavity system depends on the location of the
qubit in the cavity electromagnetic field.

The structures of adsorbed halide monolayers, e.g. chloride, iodide
as well as some organic molecules on a Cu(100) electrode have
been investigated by a combination of cyclic voltammetry (CV) and
electrochemical scanning tunneling microscopy (EC-STM). The
potential range of the copper electrode in electrolytes is limited by
two chemical reactions, (i) the oxidative copper dissolution reaction
(CDR) at the anodic limit and (ii) the reductive hydrogen evolution
reaction (HER) at the cathodic limit. While a featureless CV curve is
characteristic in pure hydrochloric acid, drastic changes in the CV
curves are observed in the iodide and organic molecules containing
solutions, indicating the formation of a two-dimensional CuI film or
redox reactions of the organic molecules. While chloride anions form
a simple c(2 x 2) structure on the Cu(100) electrode, an
electrocompressible c(p x 2) structure of adsorbed iodide is found,
which at anodic potentials at the onset of copper dissolution
transforms into the two-dimensional CuI compound. Using the
respective halide covered and modified Cu(100) surface as a
template for the adsorption of the organic molecules the dynamics of
the adsorption process and the structure of the co-adsorbed
porphyrin layers has been investigated with submolecular resolution.
The results not only provide data about the structure of the adsorbed
organic overlayer but also enable its correlation with the template
structure underneath. Based on these informations structure models
are proposed for the various adsorbate layers which could serve as
input in theoretical simulations.

Besides being of fundamental interest, entanglement is an important
resource in quantum communication and information processing. The
properties of the entanglement in many-body systems have attracted
much attention recently. Using separability conditions in the form of
inequalities derived by Hillery and coworkers, we explore the bipartite
entanglement in noninteracting Fermi gas and Bardeen–Cooper–
Schrieffer (BCS) superconducting systems at zero temperature. It is
shown that these conditions can detect entanglement between two
particles at different positions in the ground state of a Fermi gas and
between two particles within an electron pair in the ground state of a
BCS system.

In this work, we study the Casimir force F between two parallel
ferromagnetic plates in presence of an external magnetic field. The
magnetic field dependent dielectric permittivity of metals is described
using the Drude model approache. The dependence of the Casimir
force on magnetic field strength (via cyclotron frequency) is
calculated with different separation distances of plates, D. Results
show that the Casimir force increases as function of the cyclotron
frequency with a parabolic law. We also investigate the effect of the
magnetic field direction (defined by the angle, φ, between the
magnetic field direction and the surface normal of the plates) on the
Casimir force at different distances D. It is showed that the Casimir
force decreases when the angle φ increases by a Gaussian law.
These behaviors are discussed.

We propose a protocol for controlled quantum teleportation of
continuous variable states via trio coherents states. In our protocol,
using quadrature phase operators and photon counting, a sender is
able to teleport an arbitrary unknown coherent state to a distant
receiver, without physically sending the state itself, but with the
control of a third party, the supervisor. We present in detail two
different ways of controlling the teleportation task and compare them

The paper presents the simulation of new diffusion mechanism
assumed for tracer diffusion in the amorphous iron. This mechanism
consists in that one of the atoms around the simplex moves by a long
distance and the others by small distances. An atomic model of
amorphous iron consisting of 20000 atoms was constructed by
means of molecular dynamic and statistics relaxation method. The
pair correlation distributed function is found to be in good agreement
with experiment. The local structure of amorphous model is analyzed
through the simplex statistics. It was found that only large simplex
like microscopic bubble enables to realize such atomic movement.
Furthermore, the number of bubble-simplexes strongly depends on
the relaxation degree. The diffusion coefficient calculated for the
suggested mechanism for amorphous iron is in good agreement with
experiment. The effect of reduce of diffusion coefficient upon thermal
annealing is interpreted by the loss of the bubble-simplexes.

We use the time-dependent Ginzburg-Landau approach to
investigate nonlinear response of a strongly type-II superconductor.
The layered structure of the superconductor is accounted for by
means of the Lawrence-Doniach model. Thermal fluctuations,
represented by the Langevin white noise, are assumed to be strong
enough to melt the Abrikosov vortex lattice created by the magnetic
field into a moving vortex liquid. The nonlinear interaction term in
dynamics is treated within self-consistent Gaussian approximation.
The resistivity beyond linear response is calculated for arbitrary
temperature, and electric field. Our results include all Landau levels.
The application of strong electric fields results in a slightly stronger
suppression of the superconducting
fluctuations.

The alkali-metal diatomic molecules have been attractive for both
theoreticians and experimentalists because they have a relatively simple
electronic structure. Their electronic structure is frequently considered by
theoreticians as a very convenient model for introducing approximations
which can be further applied to more complex molecular systems. From
the experimental point of view, alkali-metal diatomic molecules with their
main absorption bands lying in the visible and UV regions are very
convenient objects for investigations with modern laser spectroscopy
techniques. Investigations of alkali-metal molecules have recently
experienced additional impetus since the formation of molecular BoseEinstein condensates [1]. As in several experimental techniques related to
cold molecules involve optical excitation either in the formation or
detection stages, an accurate need of precise spectroscopic
characterization of excited molecular states has arisen.
Among alkali-metal diatomic molecules, NaLi is particularly interested
there because it has permanent dipole moment, thus can therefore
be manipulated with external electric fields. Experimental
investigations for the NaLi molecule, however, encounter two
dilemmatic problems. The first one is the spectral overlaps due to a
large number of allowed electric dipole transitions between various
rovibrational energy levels. The second one is the difficulty in
producing NaLi molecules is gas phase due to a big difference in
melting-point temperatures between Na and Li bulks. Up to date,
number of studied electronic states is quite limited [3-8]. As was
suggested by the Schawlow’s group, the problem for spectroscopic
overlaps could be surmounted by using the so called polarization
labelling spectroscopy (PLS) technique [2]. Although the polarization
spectra are Doppler limited but they are greatly simplified due to
labelling process.
In this work, we present our PLS observation for NaLi. Over 800
spectral lines, which local up to near dissociation limit, have been
identified. To our knowledge, this is the first time the rotational
structure of NaLi in the 21 state has been resolved.
