#### 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 ...

#### Collective modes in a bilayer dipolar fermi gas and the dissipationless drag effect

(Springer, 2013)

We consider the collective modes of a bilayer dipolar Fermi system in which the particles interact via long range (∼1/r 3) interaction. Assuming that each layer has a background flow which varies little and that the dynamics ...

#### Two-dimensional boson-fermion mixtures in harmonic traps

(Elsevier Science B.V., 2003)

The density profiles of bosonic and fermionic components in a system of trapped two-dimensional (2D) boson-fermion (BF) mixture are studied. We employ the variational approach to minimize the total energy functional of the ...

#### Quasi-particle properties in a quasi-two-dimensional electron liquid

(Indian Academy of Sciences, 2008)

We consider the quasi-particle properties such as the effective mass and spin susceptibility of quasi-two-dimensional electron systems. The finite quantum well width effects are incorporated into the local-field factors ...

#### Electronic transmittance phase extracted from mesoscopic interferometers

(2012)

The usual experimental set-up for measuring the wave function phase shift of electrons tunneling through a quantum dot (QD) embedded in a ring (i.e., the transmittance phase) is the so-called 'open' interferometer as first ...

#### Non-equilibrium transport and spin dynamics insingle-molecule magnets.

(Academic Press, 2015)

The time-dependent transport through single-molecule magnets (SMM) coupled to mag-netic or non-magnetic electrodes is studied in the framework of the generalized Masterequation (GME) method. We calculate the transient ...
