Matter-wave vortices in cigar-shaped and toroidal waveguides
Luca Salasnich, Flavio Toigo, Boris A. Malomed
We study vortical states in a Bose-Einstein condensate (BEC) filling a cigar-shaped trap. An effective one-dimensional (1D) nonpolynomial Schroedinger equation (NPSE) is derived in…
Shell Effects in the First Sound Velocity of an Ultracold Fermi Gas
Luca Salasnich, Flavio Toigo
We investigate the first sound of a normal dilute and ultracold two-component Fermi gas in a harmonic microtube, i.e. a cylinder with harmonic transverse radial confinement in the…
One-dimensional superfluid Bose-Fermi mixture: mixing, demixing and bright solitons
Sadhan K. Adhikari, Luca Salasnich
We study a ultra-cold and dilute superfluid Bose-Fermi mixture confined in a strictly one-dimensional atomic waveguide by using a set of coupled nonlinear mean-field equations obta…
Kirzhnits gradient expansion for a D-dimensional Fermi gas
Luca Salasnich
For an ideal D-dimensional Fermi gas under generic external confinement we derive the correcting coefficient of the von Weizsacker term in the kinetic energy density. To…
Condensate Fraction of a Two-Dimensional Attractive Fermi Gas
Luca Salasnich
We investigate the Bose-Einstein condensation of fermionic pairs in a two-dimensional uniform two-component Fermi superfluid obtaining an explicit formula for the condensate densit…
Mixing-demixing transition and collapse of a vortex state in a quasi-two-dimensional boson-fermion mixture
Sadhan K. Adhikari, Luca Salasnich
We investigate the mixing-demixing transition and the collapse in a quasi-two-dimensional degenerate boson-fermion mixture (DBFM) with a bosonic vortex. We solve numerically a quan…
Nearly-one-dimensional self-attractive Bose-Einstein condensates in optical lattices
L. Salasnich, A. Cetoli, B. A. Malomed +1
Within the framework of the mean-field description, we investigate atomic Bose-Einstein condensates (BECs), with attraction between atoms, under the action of strong transverse con…
Self-bound droplet of Bose and Fermi atoms in one dimension: Collective properties in mean-field and Tonks-Girardeau regimes
Luca Salasnich, Sadhan K. Adhikari, Flavio Toigo
We investigate a dilute mixture of bosons and spin-polarized fermions in one-dimension. With an attractive Bose-Fermi scattering length the ground-state is a self-bound droplet, i.…
Self-induced density modulations in the free expansion of Bose-Einstein condensates
L. Salasnich, N. Manini, F. Bonelli +2
We simulate numerically the free expansion of a repulsive Bose-Einstein condensate with an initially Gaussian density profile. We find a self-similar expansion only for weak inter-…
Fermi-Bose mixture across a Feshbach resonance
Luca Salasnich, Flavio Toigo
We study a dilute mixture of degenerate bosons and fermions across a Feshbach resonance of the Fermi-Fermi scattering length . This scattering length is renormalized by the bo…
