Collective excitations and screened interactions in two-dimensional charged Bose systems
(Institute of Physics Publishing Ltd., 1995)We study the collective excitation spectrum of a two-dimensional charged Bose gas interacting via long- and short-range potentials. The resulting plasmon dispersions depend on the type of interaction. Extending our results ... -
Drag effect for a bilayer charged-Bose-gas system
(American Physical Society, 1996)The Coulomb-drag effect, which has previously been considered theoretically and experimentally for a system of two electron gas layers, is studied for a system of two charged-Bose-gas (CBG) layers within an analytically ... -
Effects of disorder on collective modes in single-and double-layer Bose systems
(Institute of Physics Publishing Ltd., 1996)We report some new results from our study of two-dimensional (2D) Bose systems, particularly the collective excitations in 2D charged Bose gas, in the presence of disorder. The effects of disorder are taken into account ... -
Many-body properties of a disordered charged Bose gas superlattice
(Academic Press, 2000)We study some many-body properties of a disordered charged Bose gas (CBG) superlattice-an infinite array of CBG layers each of which containing disorder. The latter is assumed to cause collisions with the charged bosons, ... -
Self-consistent theory of localization and Coulomb drag effect
(American Physical Society, 2000)We study the Coulomb drag rate for electrons in a double-quantum-well structure in the presence of disorder. The self-consistent theory of localization is used to obtain the frequency dependence of the generalized diffusion ...
