Coulomb drag effect in parallel quantum dots
(American Institute of Physics, 2009)
We study theoretically the electronic transport in parallel few-level quantum dots in the presence of both intradot and interdot long-range Coulomb interaction. Each dot is connected to two leads and the steady-state ...
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 ...
Density functional theory investigation of two-dimensional dipolar fermions in a harmonic trap
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 ...
Drag effect in double-layer dipolar fermi gases
We consider two parallel layers of two-dimensional spin-polarized dipolar Fermi gas without any tunneling between the layers. The effective interactions describing screening and correlation effects between the dipoles in ...
Analysis of the phase lapse problem in closed interferometers
(Elsevier B.V., 2012)
We investigate the connection between the asymmetry of the Fano resonances in a mesoscopic interferometer with an embedded quantum dot and the π lapses in the phase of the bare dot transmittance. Consecutive Fano resonances ...
Quantum turnstile operation of single-molecule magnets
(Institute of Physics Publishing, 2015)
The time-dependent transport through single-molecule magnets coupled to magnetic or non-magnetic electrodes is studied in the framework of the generalized master equation method. We investigate the transient regime induced ...
Mesoscopic Fano effect in a spin splitter with a side-coupled quantum dot
(Elsevier B.V., 2012)
We investigate the interplay between the spin interference and the Fano effect in a three-lead mesoscopic ring with a side-coupled quantum dot (QD). A uniform Rashba spin-orbit coupling and a perpendicular magnetic field ...
Raman superradiance and spin lattice of ultracold atoms in optical cavities
(IOP Institute of Physics Publishing, 2013)
We investigate the synthesis of a hyperfine spin lattice in an atomic Bose-Einstein condensate, with two hyperfine spin components, inside a one-dimensional high-finesse optical cavity, using off-resonant superradiant Raman ...

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 ...
