TLDR
In this paper, the authors consider the atomic dynamics and the optical response of the medium to a continuous-wave laser and show how coherently prepared media can be used to improve frequency conversion in nonlinear optical mixing experiments.Abstract:
Coherent preparation by laser light of quantum states of atoms and molecules can lead to quantum interference in the amplitudes of optical transitions. In this way the optical properties of a medium can be dramatically modified, leading to electromagnetically induced transparency and related effects, which have placed gas-phase systems at the center of recent advances in the development of media with radically new optical properties. This article reviews these advances and the new possibilities they offer for nonlinear optics and quantum information science. As a basis for the theory of electromagnetically induced transparency the authors consider the atomic dynamics and the optical response of the medium to a continuous-wave laser. They then discuss pulse propagation and the adiabatic evolution of field-coupled states and show how coherently prepared media can be used to improve frequency conversion in nonlinear optical mixing experiments. The extension of these concepts to very weak optical fields in the few-photon limit is then examined. The review concludes with a discussion of future prospects and potential new applications.read more

Exact methods in the analysis of the non-equilibrium dynamics of integrable models: application to the study of correlation functions for non-equilibrium 1D Bose gas
TL;DR: In this article, the authors study the non-equilibrium dynamics of one-dimensional Bose gas from the general perspective of the dynamics of integrable systems and develop a numerical procedure which allows explicit summation over intermediate states and analysis of the time evolution of non-local density correlation functions.

Electromagnetically Induced Transparency
TL;DR: In this article, the principles of the electromagnetically induced transparency (EIT) in basic three-level schemes are sketched, and some applications of this phenomenon are described, and a presentation follows of a five-level EIT model of Bloch equations, which was developed to reconstruct multipeak cascade-EIT spectra registered in a sample of cold 85 Rb atoms in MOT.

Waveguide-coupled surface plasmon resonance sensor structures: Fano lineshape engineering for ultrahigh-resolution sensing
TL;DR: In this paper, the authors analyzed the plasmon-induced transparency and Fano resonance exhibited by a waveguide-coupled surface plasmor resonance sensor structure and showed that the results of electromagnetic calculations made for the structure agree very well with those of mechanical calculations made by two coupled harmonic oscillators.

Light Stops at Exceptional Points
TL;DR: It is shown that zero group speed in PT symmetric optical waveguides can be achieved if the system is prepared at an exceptional point, where two optical modes coalesce.

Effects of Configuration Interaction on Intensities and Phase Shifts
TL;DR: In this paper, a theoretical analysis of the shape of the 2s2p^{1}P resonance of He observed in the inelastic scattering of electrons is presented. But the analysis is restricted to the case of one discrete level with two or more continua and of a set of discrete levels with one continuum.
