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-…
Extended Thomas-Fermi Density Functional for the Unitary Fermi Gas
Luca Salasnich, Flavio Toigo
We determine the energy density and the gradient correction of the extended Thomas-Fermi (ETF) density functional, where is number…
DC Josephson Effect with Fermi gases in the Bose-Einstein regime
F. Ancilotto, L. Salasnich, F. Toigo
We show that the DC Josephson effect with ultracold fermionic gases in the BEC regime of composite molecules can be described by a nonlinear Schrodinger equation (NLSE). By compari…
Dynamics of kicked matter-wave solitons in an optical lattice
A. Cetoli, L. Salasnich, B. A. Malomed +1
We investigate effects of the application of a kick to one-dimensional matter-wave solitons in a self-attractive Bose-Einstein condensate trapped in a optical lattice. The resultin…
Hydrodynamics of Bose and Fermi superfluids at zero temperature: the superfluid nonlinear Schrodinger equation
Luca Salasnich
We discuss the zero-temperature hydrodynamics equations of bosonic and fermionic superfluids and their connection with generalized Gross-Pitaevskii and Ginzburg-Landau equations th…
