INVESTIGATION OF QUANTUM FLUCTUATIONS IN A NONLINEAR INTERFEROMETER WITH HARMONIC GENERATION AND COHERENT INTERACTION OF LIGHT AND CS ATOMS
optics A NONLINEAR INTERFEROMETER
2015/1/19
In the first part of this thesis, we investigate the propagation of quantum fluctuations
in a nonlinear interferometer comprising under conditions of harmonic generation
by computer simulations. Thi...
Diagrammatic pump-probe approach to coherent backscattering of laser light by cold atoms: Double scattering revisited
Diagrammatic pump-probe coherent backscattering of laser light cold atoms Double scattering revisited Atomic Physics
2012/4/20
We present a diagrammatic derivation of the coherent backscattering spectrum from two two-level atoms using the pump-probe approach, wherein the multiple scattering signal is deduced from single-atom ...
Polarization squeezing of light by single passage through an atomic vapor
Polarization squeezing single passage atomic vapor
2011/8/17
Abstract: We have studied relative-intensity fluctuations for a variable set of orthogonal elliptic polarization components of a linearly polarized laser beam traversing a resonant $^{87}$Rb vapor cel...
Fine structure of helium and light helium-like ions
Fine structure helium light helium-like ions
2010/11/16
Calculational results are presented for the fine-structure splitting of the 2^3P state of helium and helium-like ions with the nuclear charge Z up to 10. Theoretical predictions are in agreement with...
The excitation of a two-level atom by a propagating light pulse
The excitation two-level atom propagating light pulse
2010/11/8
State mapping between atoms and photons, and photon-photon interactions play an important role in scalable quantum information processing. We consider the interaction of a two-level atom with a quant...
Light Scalar Mesons as Manifestation of Spontaneously Broken Chiral Symmetry
Light Scalar Mesons Spontaneously Broken Chiral Symmetry
2010/3/15
Attention is paid to the production mechanisms of light scalars that reveal their nature. We reveal the chiral shielding of the \sigma(600) meson. We show that the kaon loop mechanism of the \phi radi...
