BCS-BEC crossover in a two-dimensional Fermi gas
G. Bertaina, S. Giorgini
We investigate the crossover from Bardeen-Cooper-Schrieffer (BCS) superfluidity to Bose-Einstein condensation (BEC) in a two-dimensional Fermi gas at T=0 using the fixed-node diffu…

Itinerant ferromagnetism of a repulsive atomic Fermi gas: a quantum Monte Carlo study
S. Pilati, G. Bertaina, S. Giorgini +1
We investigate the phase diagram of a two-component repulsive Fermi gas at T=0 by means of quantum Monte Carlo simulations. For a given value of the positive s-wave scattering leng…

First and second sound in cylindrically trapped gases
G. Bertaina, L. Pitaevskii, S. Stringari
We investigate the propagation of density and temperature waves in a cylindrically trapped gas with radial harmonic confinement. Starting from two-fluid hydrodynamic theory we deri…
