Sound propagation in elongated superfluid fermion clouds
P. Capuzzi, P. Vignolo, F. Federici +1
We use hydrodynamic equations to study sound propagation in a superfluid Fermi gas inside a strongly elongated cigar-shaped trap, with main attention to the transition from the BCS…
Phase diagram of spin-1 bosons on one-dimensional lattices
Matteo Rizzi, Davide Rossini, Gabriele De Chiara +2
Spinor Bose condensates loaded in optical lattices have a rich phase diagram characterized by different magnetic order. Here we apply the Density Matrix Renormalization Group to ac…
Temperature dependence of the energy of a vortex in a two-dimensional Bose gas
K. K. Rajagopal, B. Tanatar, P. Vignolo +1
We evaluate the thermodynamic critical angular velocity Omega_c(T) for creation of a vortex of lowest quantized angular momentum in a strictly two-dimensional Bose gas at temperatu…
Effects of collisions against thermal impurities in the dynamics of a trapped fermion gas
P. Capuzzi, P. Vignolo, F. Toschi +2
We present a theoretical study of the dynamical behavior of a gas made of ultracold fermionic atoms, which during their motions can collide with a much smaller number of thermal bo…
