Coupled plasmon-LO-phonon modes in GaInAs quantum wires
(American Institute of Physics., 1996-06-20)
We study the collective excitation modes of coupled quasi-one-dimensional electron gas and longitudinal-optical phonons in GaInAs quantum wires within the random-phase approximation. In contrast to the higher-dimensional ...
Light-hole exciton mixing and dynamics in Mn-doped quantum dots
(American Physical Society, 2016)
We investigate theoretically the spectral and dynamical effects of the short-range exchange interaction between a single manganese (Mn) atom hosted by cylindrical CdTe quantum dots and its light-hole excitons or biexcitons. ...
Density-wave instability and collective modes in a bilayer system of antiparallel dipoles
(IOP Publishing, 2018-01)
We consider a bilayer of dipolar particles in which the polarization of dipoles is perpendicular to the planes, in the antiparallel configuration. Using accurate static structure factor S q( ) data from hypernetted-chain ...
Coulomb drag in parallel quantum dots
(Europhysics Letters Association, 2009-07-9)
We study theoretically the electronic transport in parallel few-level quantum dots in the presence of both intradot and interdot long-range Coulomb interaction. Each dot is connected to two leads and the steady-state ...
Dielectric screening effects on electron transport in Ga0.51In0.49P/InxGa1-xAs/GaAs quantum wells
(American Institute of Physics, 2000-04-18)
The effects of dielectric screening on the two dimensional polar optical phonon scattering and on electron transport in Ga0.51In0.49P/InxGa1-xAs/GaAs (x=0, 0.15, and 0.25) modulation doped heterostructures and high electron ...
Effects of disorder on the ground-state energy of a two-dimensional electron gas
(The American Physical Society, 2002)
We study the effects of disorder scattering on the ground-state energy of a two-dimensional electron system.Considering charged impurity scattering within the mode-coupling approximation to the memory ...
Bistable behavior of a two-mode Bose-Einstein condensate in an optical cavity
(IOP Institute of Physics Publishing, 2013-01-11)
We consider a two-component Bose-Einstein condensate in a one-dimensional optical cavity. Specifically, the condensate atoms are taken to be in two degenerate modes due to their internal hyperfine spin degrees of freedom ...
Effects of screening on the two-dimensional electron transport properties in modulation doped heterostructures
The effects of screening on the polar optical phonon scattering rates and on the transport properties of the two-dimensional electron gas in AlGaAs/GaAs modulation doped heterostructures have been investigated through Monte ...
Different scattering regimes in two-dimensional Bose-Einstein condensates
Motivated by the recent efforts to produce low-dimensional condensates, we study the ground-state density profiles of two-dimensional Bose-Einstein condensed atoms at zero temperature within a mean-field theory. The interplay ...
Effect of Superconductivity–Magnetism Interaction on the Differential Conductivity in Ho(NiB)2C/Ag Point Contacts
(M A I K Nauka - Interperiodica, 2002)
In terms of the Blonder–Tinkham–Klapwjik theory, the differential conductivity of Ho(NiB)2C/Agpoint contacts is explained by the coexistence of magnetic ordering and superconductivity in holmium boroncarbides.
