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 briefly review the research on second sound in ultracold atomic physics, with emphasis
on strongly interacting unitary Fermi gases with infinitely large s-wave scattering length …

Understanding how strongly correlated two-dimensional (2D) systems can give rise to
unconventional superconductivity with high critical temperatures is one of the major …

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

We numerically study the transport properties of a two-dimensional Fermi gas in a weakly
and strongly interacting regimes, in the range of temperatures close to the transition to a …

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 investigate the electron-hole two-stream instability (or Coulomb drag) in bilayer
graphene in the hydrodynamic regime, accounting for the effects of temperature, initial drift …

We study the propagation of the two sound modes in two-dimensional Bose gases across
the Berezinksii–Kosterlitz–Thouless transition using classical-field dynamics, which is …

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 …

Multicomponent superfluidity exhibits fruitful physics in contrast to single-component
superfluids. In a binary superfluid with two different hyperfine states, the vorticity is modified …
