Phase diffusion pattern in quantum nondemolition systems
... As stated above, in the context of energy-preserving QND systems, the only effect of the environment on the system is dephasing and it is a natural question to ask about the pattern of diffusion of ‘phases’ in such a situation. Such a question is particularly relevant in the context of a number of p ...

Quantum Critical Systems from ADS/CFT

The AdS/CFT (anti-de Sitter/conformal field theory) correspondence enables us to construct some strongly coupled quantum field theories by means of general relativity, and this approach provides new universality classes of condensed matter systems. In this dissertation, we will consider three system ...

Dyson equation for diffractive scattering

Starting from a Dyson equation for the semiclassical Green’s function we develop a diagrammatic expansion that allows a systematic summation over classical and pseudopaths, the latter consisting of classical paths joined by diffractive scatterings ...

Effects of photonic structures on upconversion

These values are considerably higher than what has been calculated for the influence of plasmon resonances in gold nanopar ...

Hydrogen atom
A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force. Atomic hydrogen constitutes about 75% of the elemental (baryonic) mass of the universe.In everyday life on Earth, isolated hydrogen atoms (usually called ""atomic hydrogen"" or, more precisely, ""monatomic hydrogen"") are extremely rare. Instead, hydrogen tends to combine with other atoms in compounds, or with itself to form ordinary (diatomic) hydrogen gas, H2. ""Atomic hydrogen"" and ""hydrogen atom"" in ordinary English use have overlapping, yet distinct, meanings. For example, a water molecule contains two hydrogen atoms, but does not contain atomic hydrogen (which would refer to isolated hydrogen atoms).
