#### Light-hole exciton mixing and dynamics in Mn-doped quantum dots

(American Physical Society, 2016)

We investigate theoretically the spectral and dynamical effects of the short-range exchange interaction between a single manganese (Mn) atom hosted by cylindrical CdTe quantum dots and its light-hole excitons or biexcitons. ...

#### Density-wave instability and collective modes in a bilayer system of antiparallel dipoles

(IOP Publishing, 2018-01)

We consider a bilayer of dipolar particles in which the polarization of dipoles is perpendicular to the
planes, in the antiparallel configuration. Using accurate static structure factor S q( ) data from
hypernetted-chain ...

#### Bistable behavior of a two-mode Bose-Einstein condensate in an optical cavity

(IOP Institute of Physics Publishing, 2013-01-11)

We consider a two-component Bose-Einstein condensate in a one-dimensional optical cavity. Specifically, the condensate atoms are taken to be in two degenerate modes due to their internal hyperfine spin degrees of freedom ...

#### Effect of weak disorder on the BCS-BEC crossover in a two-dimensional Fermi gas

(World Scientific Publishing Co. Pte Ltd, 2017)

In this paper, we study the two-dimensional (2D) ultracold Fermi gas with weak impurity in the framework of mean-field theory where the impurity is introduced through Gaussian fluctuations. We have investigated the role ...

#### Disorder Induced BCS-BEC Crossover in an Ultracold Fermi Gas

(Springer, 2013-05)

We develop the formalism for BCS-BEC crossover in the presence of weak random impurity and calculate the effect of the random potentials on the basic mean-field quantities. The disorder has been included through the Nozieres ...

#### Unpinning of heavy hole spin in magnetic quantum dots

(Wiley-VCH Verlag, 2017)

Using the k · p theory and configuration interaction method, we analyze the effect of heavy hole–light hole (HH–LH) mixing in CdTe quantum dots (QDs) with a single manganese (Mn) ion. We find that the hole-Mn exchange ...

#### Investigating dirty crossover through fidelity suscepribility and density of states

(World Scientific Publishing, 2014)

We investigate the BCS-BEC crossover in an ultracold atomic gas in the presence of disorder. The disorder is incorporated in the mean-field formalism through Gaussian fluctuations. We observe evolution to an asymmetric ...

#### 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 ...

#### Energy transfer in a bilayer Fermi gas in the non-linear regime

(Wiley-VCH Verlag, 2017)

We consider a bilayer system of two-dimensional spin-polarized dipolar Fermi gas without any tunneling between the layers. We calculate the energy transfer rate between the layers in the nonlinear regime where the layers ...

#### Phase diagram and dynamics of Rydberg-dressed fermions in two dimensions

(American Physical Society, 2017)

We investigate the ground-state properties and the collective modes of a two-dimensional two-component Rydberg-dressed Fermi liquid in the dipole-blockade regime. We find instability of the homogeneous system toward ...
