Dynamical classical superfluid-insulator transition in a Bose-Einstein condensate on an optical lattice
(Iop Publishing Ltd, 2003-07-14)
We predict a dynamical: classical superfluid-insulator transition in a Bose-Einstein condensate (BEC) trapped in combined optical and axially symmetrical harmonic potentials initiated by the periodic modulation of the ...
Nonlinear Schrodinger equation for a superfluid Fermi gas in the BCS-BEC crossover
(Amer Physical Soc, 2008-04-01)
We introduce a quasianalytic nonlinear Schrodinger equation with beyond mean-field corrections to describe the dynamics of a zero-temperature dilute superfluid Fermi gas in the crossover from the weak-coupling Bardeen-Co ...

Effective nonlinear Schrodinger equations for cigar-shaped and disc-shaped Fermi superfluids at unitarity
(Iop Publishing Ltd, 2009-02-06)
In the case of tight transverse confinement (cigar-shaped trap), the three-dimensional (3D) nonlinear Schrodinger equation, describing superfluid Fermi atoms at unitarity (infinite scattering length vertical bar a vertical ...

Extended fluid-dynamics and collective motion of two trapped fermion species with pairing interactions
(Springer/Plenum Publishers, 2011-02)
We extend our earlier fluid-dynamical description of fermion superfluids incorporating the particle energy flow together with the equation of motion for the internal kinetic energy of the pairs. The formal scheme combines ...
Cold fermions with pairing interactions: New results based on fluiddynamical descriptions
(Springer/Plenum Publishers, 2012-02)
We present a rigorous derivation of the moment hierarchy of the density and pair density matrices of a two species fermion superfluid in coordinate representation. We discuss the tools to truncate at any desired level and ...
Vortex dynamics in Bose-Einstein condensates: Numerical calculations
(SP MAIK Nauka/Interperiodica, 2009-04)
We numerically study properties of the dynamics of vortices in nonrotating Bose-Einstein condensates in the Thomas-Fermi regime. On the one hand, we compute the vortex energy as a function of its position and we predict, ...
