We review the quantum statistical properties of two-dimensional shell-shaped gases,
produced by cooling and confining atomic ensembles in thin hollow shells. We consider …

We theoretically investigate the superfluid–normal-state Berezinskii-Kosterlitz-Thouless
transition in a binary mixture of bosonic atoms with Rabi coupling under balanced densities …

Recent experiments on 2D superconductors allow the characterization of the critical
temperature and of the phase diagram across the BCS-BEC crossover as a function of …

We study the amplitude and phase fluctuations of the Ginzburg-Landau quasiorder
parameter for superconductors in two spatial dimensions. Starting from the mean-field …

We review our theoretical results of the sound propagation in two-dimensional (2D) systems
of ultracold fermionic and bosonic atoms. In the superfluid phase, characterized by the …

Sound propagation is a macroscopic manifestation of the interplay between the equilibrium
thermodynamics and the dynamical transport properties of fluids. Here, for a two …

We theoretically investigate sound modes in a weakly-interacting collisional Bose gas in D
dimensions. Using the Landau's two-fluid hydrodynamics and working within the Bogoliubov …

We compare recent experimental results [Science 375, 528 (2022) 0036-8075
10.1126/science. abi4480] of the superfluid unitary Fermi gas near the critical temperature …

We study the finite-size effects on the BCS-BEC crossover in two dimensions, occurring in
confined fermionic superfluids. We analyze several thermodynamic properties, such as the …

The spatial structure of a two-dimensional homogeneous mixture of fermionic atoms in two
hyperfine states is analyzed throughout the BEC-BCS crossover. Within the BCS-Leggett …
