Two-particle asynchronous quantum correlation: wavefunction
... mirror is represented as the black rectangle, moving to the right at speed V < v. At t = t1 = τ interference between the incident and reflected particle substates is shown as oscillations in its PDF while interference between the mirror substates which have and have not reflected the particle is rep ...

Spin Physics in Two-dimensional Systems Daniel Gosálbez Martínez
... Graphene was the first example of a truly two dimensional (2D) crystal. This sort of materials were unexpected because it was believed that long range order due to the spontaneous breaking of a continuous symmetry in two dimensions was destroyed by long-wavelength fluctuations[1]. Since its discover ...

If a single atom and a single photon interact in a cavity resonator where they are well isolated from the environment, the coherent dipole coupling can dominate over any dissipative effects. In this strong coupling limit the atom repeatedly absorbs and emits a single quantum o ...

Multiple-User Quantum Information Theory for Optical Communication Channels Saikat Guha
... Research in the past decade has established capacity theorems for point-to-point bosonic channels with additive thermal noise, under the presumption of a conjecture on the minimum output von Neumann entropy. In the first part of this thesis, we evaluate the optimum capacity for free-space line-of-si ...

RASHBA SPIN-ORBIT INTERACTION IN MESOSCOPIC SYSTEMS Frank Erik Meijer
... In high-purity semiconductors and quantum wells electrons move ballistically, and are phase-coherent over large distances at low enough temperatures (typically > 1 µm at T ∼ 1 K). In this regime, the classical Boltzmann description of electron transport does no longer hold, and new theories were dev ...

To prove that the condition eq. (7.19) is necessary and sufficient, we invoke the theory of superoperat ...

Pinning mode resonances of single layers have be ...
