#### Dynamical correlations in Coulomb drag effect

(Elsevier, 2003)

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 ...

#### Magnetic polaritons, magnetostatic waves and effective-medium approximation for antiferromagnetic superlattice with impurity in parallel magnetic field

(Springer, 2012)

We derive the general effective-medium expression for the surface-guided magnetic polaritons and magnetostatic waves, which propagate in the antiferromagnetic superlattice with antiferromagnetic impurity film, and investigate ...

#### Solid state communications: foreword

(Elsevier, 2002)

#### Mesoscopic Fano effect in an Aharonov-Bohm interferometer Coulomb-coupled to a nearby quantum dot

(Wiley, 2007)

Motivated by the pionieering experiments of Buks et al. [Nature 391, 871 (1998)] we investigate the visibility of the Fano effect in a single-dot Aharonov-Bohm interferometer which is Coulomb-coupled to a nearby quantum ...

#### Ground-state properties and collective excitations in a 2D Bose-Einstein condensate with gravity-like interatomic attraction

(Springer, 2008)

We study the ground-state properties of a Bose-Einstein condensate (BEC) with the short-range repulsion and gravitylike 1/r interatomic attraction in two-dimensions (2D). Using the variational approach, we obtain the ...

#### Theoretical investigations on the energy relaxation in two-dimensional GaN systems

(Wiley, 2007)

We theoretically study the energy relaxation of hot electrons via LO-phonon emission in two-dimensional GaN systems. We employ a model in which electrons and the lattice are in equilibrium separately, and the effective ...

#### Ground-state energy and compressibility of a disordered two-dimensional electron gas

(World Scientific Publishing, 2007)

Two-dimensional (2D) electron systems in the presence of disorder are of interest in connection with the observed metal-insulator transition in such systems. We use density functional theory in its local-spin density ...

#### Magnetization and spin susceptibility of an interacting two-dimensional electron gas

(American Institute of Physics, 2007)

We study the magnetic behavior and in particular the spin susceptibility of an interacting two-dimensional electron gas in a finite in-plane magnetic field. The total energy of the system is constructed using the recent ...

#### Density functional theory investigation of two-dimensional dipolar fermions in a harmonic trap

(IOP, 2014)

We investigate the behavior of polarized dipolar fermions in a two-dimensional harmonic trap in the framework of the density functional theory (DFT) formalism using the local density approximation. We treat only a few ...

#### Mesoscopic fano effect in Aharonov-Bohm rings with an embedded double dot

(American Institute of Physics, 2006)

We investigate theoretically in a tight-binding model the transport properties of the Aharonov-Bohm interferometer (ABI) with one dot embedded in each of its arms. For weak interdot coupling the model Hamiltonian describes ...
