#### Coherent and incoherent transport through T-shaped double quantum dots

(Elsevier B.V., 2008)

We investigate the measurement induced dephasing of the Fano effect in the electronic transport through a double quantum dot mesoscopic interferometer coupled to a charge detector. The current and the differential conductance ...

#### Dynamic correlations in double-layer electron systems

(The American Physical Society, 2001)

We study the effects of dynamic correlations on the ground-state properties of a double-layer two-dimensional electron gas within the quantum Singwi-Tosi-Land-Sjölander theory (STLS). The intralayer and interlayer static ...

#### Hydrodynamic approach for modelling transport in quantum well device structures

(Institute of Physics Publishing Ltd., 1998)

A semiclassical approach for modelling electron transport in quantum well structures is presented. The model is based on the balance equations governing the conservation of particle density, momentum and energy with Monte ...

#### Temperature dependence of the energy of a vortex in a two-dimensional Bose gas

(Elsevier, 2004)

We evaluate the thermodynamic critical angular velocity Ωc(T) for creation of a vortex of lowest quantized angular momentum in a strictly two-dimensional Bose gas at temperature T, using a mean-field two-fluid model for ...

#### Electric breakdown in polycrystalline semiconductors with highly nonlinear I-V characteristics: Simulations for simple barrier height models

(1997)

An extension of the Canessa and Nguyen binary model for the nonlinear current-voltage (I-V) characteristics of polycrystalline semiconductors, based on the electrical properties of individual grains, is presented. Simple ...

#### Impurity effect on the two-dimensional-electron fluid-solid transition in zero field

(American Physical Society, 1995)

We investigate the effect of impurities on the electron fluid-solid transition with parameters appropriate for the system recently studied by Pudalov et al. The nature of the crystalline state at T=0 in the presence of ...

#### 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 ...

#### Thermodynamic properties of harmonically trapped D-dimensional ideal gases within generalized exclusion statistics

(Elsevier B.V., 2007)

We consider an ideal gas trapped with harmonic potential and obeying the generalized exclusion statistics. We analytically calculate the density of states from which the thermodynamic properties of the gas are calculated ...

#### Band-gap renormalization in quantum wire systems: dynamical correlations and multi-subband effects

(Institute of Physics Publishing, 2000)

We study the band-gap renormalization m a model semiconductor quantum wire due to the exchange-correlation effects among the charge carriers. We construct a two-subband model for the quantum wire, and employ the GW-approximation ...

#### Many-body vertex corrections in a one-dimensional electron system interacting with a long-range Coulomb potential

(American Physical Society, 2000)

We study the quasiparticle properties of a one-dimensional electron gas interacting with a long-range electron-electron interaction. The electron self-energy is calculated using the leading-order dynamical-screening ...
