#### 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

(Elsevier, 1998-06)

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

(Springer, 2003)

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.
