Universal behavior of a trapped Fermi superfluid in the BCS-unitarity crossover
S. K. Adhikari
From an extensive calculation of static properties of a trapped Fermi superfluid at zero temperature using a density-functional formulation, we demonstrate a universal behavior of…
Two-component gap solitons with linear interconversion
Sadhan K. Adhikari, Boris A. Malomed
We consider one-dimensional solitons in a binary Bose-Einstein condensate with linear coupling between the components, trapped in an optical-lattice potential. The inter-species an…
Effective Nonlinear Schrödinger Equations for Cigar-Shaped and Disk-Shaped Fermi Superfluids at Unitarity
S. K. Adhikari, L. Salasnich
In the case of tight transverse confinement (cigar-shaped trap) the three-dimensional (3D) nonlinear Schrödinger equation, describing superfluid Fermi atoms at unitarity (infinite…
Superfluid Bose-Fermi mixture from weak-coupling to unitarity
S. K. Adhikari, Luca Salasnich
We investigate the zero-temperature properties of a superfluid Bose-Fermi mixture by introducing a set of coupled Galilei-invariant nonlinear Schrödinger equations valid from weak-…
Nonlinear Schrödinger equation for a superfluid Fermi gas from BCS to Bose crossover
S. K. Adhikari
We introduce a quasi-analytic nonlinear Schrödinger equation with beyond mean-field corrections to describe the dynamics of a zero-temperature dilute superfluid Fermi gas in the cr…
Tightly bound gap solitons in a Fermi gas
S. K. Adhikari, B. A. Malomed
Within the framework of the mean-field-hydrodynamic model of a degenerate Fermi gas (DFG), we study, by means of numerical methods and variational approximation (VA), the formation…
