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 ...
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.
Ground-state properties of the two-dimensional charged Bose gas
(American Physical Society, 2001-03-01)
We study the two-dimensional gas of charged bosons interacting via a logarithmic potential within the quantal hypernetted-chain approximation. The pair correlation function, the static structure factor, the groundstate ...
Hard-core Yukawa model for two-dimensional charge-stabilized colloids
(American Physical Society, 2001-10)
The hypernetted chain and Percus-Yevick approximations are used to study the phase diagram of a simple hard-core Yukawa model of charge-stabilized colloidal particles in a two-dimensional system. We calculate the static ...
Structure of a model one-dimensional liquid 3He–4He mixture
We study the ground state properties of a one-dimensional liquid 3He-4He mixture interacting via a hard-core repulsive potential at zero temperature. We use the self-consistent field approach to calculate the ground state ...
A simple model for an ultracold plasma
(Horizon Research Publishing, 2007)
We consider an ultracold plasma composed of the same number of electrons and bosonic ions, at zero temperature. We calculate the ion and electron densities taking the long range interactions into account using ...
Dynamical correlations in Coulomb drag effect
Motivated by recent Coulomb drag experiments in pairs of low-density two-dimensional (2D) electron gases, we investigate the influence of correlation effects on the interlayer drag rate as a function of temperature. We use ...
