#### Phonon confinement and screening effects on the polaron energy in quantum wires

(Institute of Physics Publishing Ltd., 1995)

We study the contribution of confined phonons to the polaron energy in quantum-well wires. We use a dispersionless, macroscopic continuum model to describe the phonon confinement in quantum wires of square cross section. ...

#### 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 ...

#### 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 ...

#### Effect of cross-sectional geometry on the RPA plasmons of quantum wires

(Pergamon Press, 1994)

The effect of cross-sectional geometry on both the intrasubband plasmon and intersubband plasmon of a quantum wire is investigated within a two-subband RPA scheme. Exact analytical electronic wavefunctions for circular, ...

#### 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 ...

#### 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 ...

#### 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 ...

#### 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 ...
