Collective Excitations of Self-Gravitating Ultralight Dark Matter Cores
Luca Salasnich, Alexander Yakimenko
A distinctive feature of ultralight bosonic dark matter is its ability to form a Bose-Einstein condensate with a dense, stationary configuration at the center of galactic halos. In…
First and second sound in two-dimensional bosonic and fermionic superfluids
L. Salasnich, A. Cappellaro, K. Furutani +2
We review our theoretical results about the sound propagation in two-dimensional (2D) systems of ultracold fermionic and bosonic atoms. In the superfluid phase, characterized by th…
Self-consistent derivation of the modified Gross-Pitaevskii equation with Lee-Huang-Yang correction
L. Salasnich
We consider a dilute and ultracold bosonic gas of weakly-interacting atoms. Within the framework of quantum field theory we derive a zero-temperature modified Gross-Pitaevskii equa…
Effective-range signatures in quasi-1D matter waves: sound velocity and solitons
F. Sgarlata, G. Mazzarella, L. Salasnich
We investigate ultracold and dilute bosonic atoms under strong transverse harmonic confinement by using a 1D modified Gross-Pitaevskii equation (1D MGPE), which accounts for the en…
Bose-Einstein condensates under a spatially-modulated transverse confinement
L. Salasnich, A. Cetoli, B. A. Malomed +2
We derive an effective nonpolynomial Schrodinger equation (NPSE) for self-repulsive or attractive BEC in the nearly-1D cigar-shaped trap, with the transverse confining frequency pe…
