#### Magnetic-field dependence of low-temperature mobility in quasi-one-dimensional electron systems

(Institute of Physics Publishing Ltd., 1994)

We study the mobility of a quasi-one-dimensional (Q1D) electron system in the presence of an axial magnetic field at low temperatures. We consider the mobility limits for remote-impurity scattering, homogeneous-background ...

#### 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 ...

#### Strongly interacting one-dimensional Bose-Einstein condensates in harmonic traps

(American Physical Society, 2000)

The properties of strongly interacting one dimensional boson condensates in harmonic trap potentials were studied. An equation describing the condensate wave function in the limit of very strong interactions between the ...

#### Analytical expressions for the local-field corrections in double-layer electron systems

(Academic Press, 1999)

We develop an extension of the sum-rule version of the Singwi, Tosi, Land, and Sjolander (STLS) scheme applied to a double-layer electron system. We present analytical expressions for the intralayer and interlayer static ...

#### Metal-insulator transition induced by random dipoles

(American Physical Society, 2013)

We study the localization properties of a test dipole feeling the disordered potential induced by dipolar impurities trapped at random positions in an optical lattice. This random potential is marked by correlations which ...

#### Vortices in trapped boson-fermion mixtures

(Springer, 2005)

We consider a trapped system of atomic boson-fermion mixture with a quantized vortex. We investigate the density profiles of bosonic and fermionic components as functions of the boson-boson and boson-fermion short-range ...

#### Many-body effects in the Coulomb drag between low density electron layers

(Elsevier Science, 2003)

Recent Coulomb drag experiments in low-density double-layer electron systems have the power of distinguishing various many-body formulations of the effective interactions. In this work we theoretically study the correlation ...

#### Confined optical phonon effects on the band gap renormalization in quantum wire structures

(Elsevier Science, 1999)

We consider the different approximations for the bandgap renormalization (BGR) within the random phase approximation (RPA), the quasi-static limit and the plasmon-pole approximation, and compare with the full result. We ...

#### 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 ...

#### Free expansion of two-dimensional condensates with a vortex

(Institute of Physics Publishing, 2003)

We study the free expansion of a pancake-shaped Bose-condensed gas, which is initially trapped under harmonic confinement and containing a vortex at its centre. In the case of a radial expansion holding the axial confinement ...
