Collapse of triaxial bright solitons in atomic Bose-Einstein condensates
G. Mazzarella, L. Salasnich
We study triaxial bright solitons made of attractive Bose-condensed atoms characterized by the absence of confinement in the longitudinal axial direction but trapped by an anisotro…
Surface Effects in the Unitary Fermi Gas
L. Salasnich, F. Ancilotto, F. Toigo
We study the extended Thomas-Fermi (ETF) density functional of the superfluid unitary Fermi gas. This functional includes a gradient term which is essential to describe accurately…
Localization of a Bose-Einstein condensate in a bichromatic optical lattice
S. K. Adhikari, L. Salasnich
By direct numerical simulation of the time-dependent Gross-Pitaevskii equation we study different aspects of the localization of a non-interacting ideal Bose-Einstein condensate (B…
Generalized nonpolynomial Schrodinger equations for matter waves under anisotropic transverse confinement
Luca Salasnich
Starting from the three-dimensional Gross-Pitaevskii equation we derive a 1D generalized nonpolynomial Schrodinger equation, which describes the dynamics of Bose-Einstein condensat…
Atomic Josephson junction with two bosonic species
Giovanni Mazzarella, Marco Moratti, Luca Salasnich +2
We study an atomic Josephson junction (AJJ) in presence of two interacting Bose-Einstein condensates (BECs) confined in a double well trap. We assume that bosons of different speci…
Solitons and solitary vortices in "pancake"-shaped Bose-Einstein condensates
Luca Salasnich, Boris A. Malomed
We study fundamental and vortical solitons in disk-morphed Bose-Einstein condensates (BECs) subject to strong confinement along the axial direction. Starting from the three-dimensi…
