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…
Unitary Fermi superfluid near the critical temperature: thermodynamics and sound modes from elementary excitations
G. Bighin, A. Cappellaro, L. Salasnich
We compare recent experimental results [Science 375, 528 (2022)] of the superfluid unitary Fermi gas near the critical temperature with a thermodynamic model based on elementary ex…
Propagation of first and second sound in a two-dimensional Fermi superfluid
A. Tononi, A. Cappellaro, G. Bighin +1
Sound propagation is a macroscopic manifestation of the interplay between the equilibrium thermodynamics and the dynamical transport properties of fluids. Here, for a two-dimension…
Effective field theory of bosons with finite-range interaction in a disordered environment
Alberto Cappellaro, Luca Salasnich
We investigate the low-temperature properties of a ultracold gas made of bosonic alkali-metal atoms with finite-range interaction under the effect of a disordered environment. The…
Dephasing-rephasing dynamics of one-dimensional tunneling quasicondensates
Andrea Tononi, Flavio Toigo, Sandro Wimberger +2
We study the quantum tunneling of two one-dimensional quasi-condensates made of alkali-metal atoms, considering two different tunneling configurations: side-by-side and head-to-tai…
Superfluids, Fluctuations and Disorder
Alberto Cappellaro, Luca Salasnich
We present a field-theory description of ultracold bosonic atoms in presence of a disordered external potential. By means of functional integration techniques, we aim to investigat…
