Squeezing in collective Raman scattering

Physics Letters A, 1988
Abstract The generation of a squeezed state via the collective Raman scattering in an intense external field is discussed. It is shown that squeezing is present only in the mixture of two sidebands of the Rayleigh line while it is absent for the Stokes line.

Collective Light Scattering: An Introduction

1994
Light scattering is one of the most common diagnostics of every day’s life. In addition to the object to be looked at, it requires only two devices, a light source, and a detector, which are both provided by the sun and the eye. The sun light that is scattered by solid body outer surfaces gives the first information we have of our environment.

Collective quantum scattering in plasma

Astroparticle Physics, 1996
Abstract Collective quantum plasma effects in scattering of photons on electrons are derived. The generalization of Klein-Nishina scattering is obtained. The dependence of scattering on the collective plasma parameter and the ratio of the photon energy to the electron thermal energy is investigated.

Collective Theory for Surface Enhanced Raman Scattering

Physical Review Letters, 1996
We present an implementation of Maxwell's equations on adaptive meshes in order to study interaction of light with metal surfaces. For the first time it is possible to handle surfaces consisting of complex particles close enough to interact strongly. A fully retarded implementation allows treatment of large particles as well as small. By way of example

Coherent neutron scattering and collective dynamics on mesoscale

The Journal of Chemical Physics, 2013
By combining, and modestly extending, a variety of theoretical concepts for the dynamics of liquids in the supercooled regime, we formulate a simple analytic model for the temperature and wavevector dependent collective density fluctuation relaxation time that is measurable using coherent dynamic neutron scattering.

Effects of the ohmic current on collective scattering spectra

Plasma Physics and Controlled Fusion, 1993
We present a numerical and analytical study of the modifications induced in the collective scattering spectra by the ohmic current governing the equilibrium magnetic configuration in toroidal plasmas. The spectral density function is calculated assuming equilibrium distributions for the (bulk and impurity) ion species and a Spitzer-like distribution to

Collective spectral properties of Raman scattering

Physica A: Statistical Mechanics and its Applications, 1987
Abstract The theory of collective Raman scattering has been developed by using the quantum-mechanical master-equation approach and secular approximation. The influence of the frequency detuning of resonance and other parameters on the collective spectral properties of scattered light is investigated.

Collective Scattering in Gases and Plasmas

1994
Plasmas are made of small size charged particles, that behave according to the reciprocal Lorentz-Maxwell electrodynamics: From Lorentz forces, particles are accelerated by electromagnetic field; and in turn, charged particle acceleration creates new e.m. waves. These new e.m.

Calibration of the collective scattering system on NSTX

2009 34th International Conference on Infrared, Millimeter, and Terahertz Waves, 2009
A multichannel 280-GHz collective scattering system has been employed to investigate electron gyro-scale density fluctuations in National Spherical Torus Experiment (NSTX) plasmas. The longitudinal scattering volume length, which is the spatial resolution of the scattering measurement, was calculated in tokamak geometry since the targeting wavenumber ...
