#### Dynamical correlations in the one-dimensional electron gas with short-range interactions

(Springer, 1999)

We study the dynamical correlation effects in a one-dimensional Fermion gas with repulsive delta-function interaction within the quantum version of the self-consistent field approximation of Singwi, Tosi, Land, and Sjölander ...

#### Energy-transfer rate in a double-quantum-well system due to Coulomb coupling

(Elsevier, 2002)

We study the energy-transfer rate for electrons in a double-quantum-well structure, where the layers are coupled through screened Coulomb interactions. The energy-transfer rate between the layers (similar to the Coulomb ...

#### 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. ...

#### Electronic transmittance phase extracted from mesoscopic interferometers

(2012)

The usual experimental set-up for measuring the wave function phase shift of electrons tunneling through a quantum dot (QD) embedded in a ring (i.e., the transmittance phase) is the so-called 'open' interferometer as first ...

#### 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 ...

#### RPA approach to non-linear transport in quantum dots

(World Scientific, 2009)

An accurate theoretical treatment of electron-electron interactions in mesoscopic systems is available in very few cases and approximation schemes are developed in most of the applications, especially for many-level quantum ...

#### Hard-core Yukawa model for charge-stabilized colloids

(American Physical Society, 2000)

The hypernetted chain approximation is used to study the phase diagram of a simple hardcore Yukawa model of a charge-stabilized colloids. We calculate the static structure factor, the pair distribution function, and the ...

#### Dependence of the cloud size on interactions for a trapped degenerate ultracold plasma

(Elsevier B.V., 2006)

We consider an ultracold plasma that has bosonic ions, at zero temperature. Assuming that ions are trapped by a harmonic trap, we calculate the size of the cloud for both screened and bare Coulomb interactions. Our results ...

#### Localized magnetic polaritons in antiferromagnetic superlattice with impurity

(2009)

The dispersion relation for magnetic polaritons localized at the antiferromagnetic impurity film in the antiferromagnetic superlattice (antiferromagnetic/nonmagnetic or antiferromagnetic/antiferromagnetic) are derived in ...
