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...
Quantum fluctuations in planar domain-wall space-times: A possible origin of primordial preferred direction
Quantum fluctuations planar domain-wall space-times possible origin primordial preferred direction
2011/10/18
We study the gravitational effects of a planar domain wall on quantum fluctuations of a massless scalar field during inflation. By obtaining an exact solution of the scalar field equation in de Sitter...
Quantum fluctuations in the effective pseudospin-1/2 model for magnetic pyrochlore oxides
effective pseudospin-1/2 model magnetic pyrochlore oxides
2010/11/25
The e ective quantum pseudospin-1=2 model for interacting rare-earth magnetic moments, which
are locally described with atomic doublets, is studied theoretically for magnetic pyrochlore oxides.It is ...
Quantum fluctuations can promote or inhibit glass formation
Quantum fluctuations can glass formation
2010/11/17
The very nature of glass is somewhat mysterious: while relaxation times in glasses are of
sufficient magnitude that large-scale motion on the atomic level is essentially as slow as it is in the cryst...
Macroscopic quantum tunneling in multigap superconducting Josephson junctions: Escape rate enhancement via quantum fluctuations of Josephson-Leggett mode
Macroscopic quantum superconducting Josephson Escape rate enhancement Josephson-Leggett mode
2010/11/5
We theoretically study the macroscopic quantum tunneling (MQT) in a hetero Josephson junction formed by a conventional single-gap superconductor and a multi-gap one such as ${MgB}_{2}$ and iron-based...
Quantum Fluctuations Contribution to the Random Walk of a Single Molecule and New Estimate of the Planck Constant
Quantum Fluctuations Random Walk Planck Constant
2010/3/10
It is shown, by considering the case of the harmonic oscillator, that quantum fluctuations may be the most significant contribution to the random walk of a single molecule. From this point, the contro...
