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…
Effects of trap anisotropy on impurity scattering regime in a Fermi gas
P. Capuzzi, P. Vignolo, M. P. Tosi
We evaluate the low-lying oscillation modes and the ballistic expansion properties of a harmonically trapped gas of fermionic K40 atoms containing thermal Rb87 impurities as functi…
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…
Condensate localization in a quasi-periodic structure
Y. Eksioglu, P. Vignolo, M. P. Tosi
We propose a set-up of optical laser beams by which one may realize a quasi-one-dimensional Fibonacci array of potential wells for a Bose-Einstein condensate. We use a Bose-Hubbard…
Transition to hydrodynamics in colliding fermion clouds
F. Toschi, P. Capuzzi, S. Succi +2
We study the transition from the collisionless to the hydrodynamic regime in a two-component spin-polarized mixture of 40K atoms by exciting its dipolar oscillation modes inside ha…
