#### 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 ...

#### Effect of disorder on the interacting fermi gases in a one-dimensional optical lattice

(World Scientific Publishing Co., 2008)

Interacting two-component Fermi gases loaded in a one-dimensional (1D) lattice and subjected to a harmonic trapping potential exhibit interesting compound phases in which fluid regions coexist with local Mott-insulator ...

#### The ground state and vortices in a two-dimensional Bose gas confined in a harmonic trap

(Institute of Physics Publishing, 2002)

We study the ground state properties of a two-dimensional Bose gas in an harmonic trap potential using the recently proposed mean-field equation that takes into account the correct dimensionality effect. In contrast to the ...

#### 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 ...

#### 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 ...

#### Compressibility of a two-dimensional electron gas in a parallel magnetic field

(Elsevier B.V., 2007)

The thermodynamic compressibility of a two-dimensional electron system in the presence of an in-plane magnetic field is calculated. We use accurate correlation energy results from quantum Monte Carlo simulations to construct ...

#### 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 ...

#### q-Gaussian trial function in high density Bose-Einstein condensates

(Elsevier Science B.V., 2003)

We study the ground-state static properties of Bose-Einstein condensates in the high density regime using a trial wave function of the form of a q-Gaussian. The flexibility afforded by a q-Gaussian trial function yields ...

#### Correlation effects in a one-dimensional electron gas with short-range interaction

(Pergamon Press, 1999)

We study the correlation effects in a one-dimensional electron gas with repulsive delta-function interaction. The correlation effects are described by a local-field correction which takes into account the short-range ...

#### Many-body properties of a disordered charged Bose gas superlattice

(Academic Press, 2000)

We study some many-body properties of a disordered charged Bose gas (CBG) superlattice-an infinite array of CBG layers each of which containing disorder. The latter is assumed to cause collisions with the charged bosons, ...
