Local fields in solids: microscopic aspects for dielectrics
TLDR
In this article, the local field problem in dielectric dielectrics is introduced and a microscopic approach to the problem is discussed. And momentum dependence is introduced for electron-phonon coupling in quasi-two-dimensional systems.Abstract:
The authors offer a historical and pedagogical introduction to the local-field problem in dielectrics. They then discuss a microscopic approach to the problem and introduce momentum dependence. Finally they apply these results to electron-phonon coupling in quasi-two-dimensional systems, in particular the high-${T}_{c}$ superconductors.read more

Resonant multiple scattering of light
TL;DR: In this article, a new approach towards resonant interaction between classical light and matter is presented, where the interaction between light and material is considered from three different points of view: the light picture where the material degrees of freedom have been integrated out, and leaving one with scattering theory, the matter picture (where the radiative degree of freedom has been eliminated and providing one essentially with atomic physics).

Coherent Scattering of Near-Resonant Light by a Dense Microscopic Cold Atomic Cloud.
Stephan Jennewein,Mondher Besbes,Nick Schilder,Stewart D. Jenkins,Christophe Sauvan,Janne Ruostekoski,Jean-Jacques Greffet,Yvan R. P. Sortais,Antoine Browaeys +8 more
TL;DR: The description of the atomic cloud by a mean-field model based on the Lorentz-Lorenz formula that ignores scattering events where light is scattered recurrently by the same atom and by a microscopic discrete dipole model that incorporates these effects lead to progressively closer agreement with the observations, despite remaining differences.

The Interaction of Radio-Frequency Fields With Dielectric Materials at Macroscopic to Mesoscopic Scales
James R. Baker-Jarvis,Sung Kim +1 more
TL;DR: Radio-frequency (RF) electromagnetic interactions with solid and liquid materials from the macroscale to the nanoscale is overviewed, and wavelength and material length scales required to define permittivity in materials are discussed.

The two-dimensional Bose Gas in box potentials
TL;DR: In this article, a degenerate 2D Bose gas with uniform in-plane confinement is studied, and a series of experiments that take advantage of this flexible geometry are presented, including the static and dynamic behaviors of a uniform gas at the transition between a 3D normal and a 2D superfluid state.

Landau ghosts and anti-ghosts in condensed matter and high density hadronic matter
TL;DR: In this paper, it is observed that the ghost and its counterparts in other theories are ubiquitous as they occur in a one-loop approximation to any conventional (unbroken) gauge theory and the physical phase transition phenomenon associated with it is found to be super-radiance.
