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…
Many-body effective mass enhancement in a two-dimensional electron liquid
R. Asgari, B. Davoudi, M. Polini +3
Motivated by a large number of recent magnetotransport studies we have revisited the problem of the microscopic calculation of the quasiparticle effective mass in a paramagnetic tw…
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…
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…
Collective modes and ballistic expansion of a Fermi gas in the BCS-BEC crossover
Hui Hu, A. Minguzzi, Xia-Ji Liu +1
We evaluate the frequencies of collective modes and the anisotropic expansion rate of a harmonically trapped Fermi superfluid at varying coupling strengths across a Feshbach resona…
Collective oscillations of a confined Bose gas at finite temperature in the random-phase approximation
Xia-Ji Liu, Hui Hu, A. Minguzzi +1
We present a theory for the linear dynamics of a weakly interacting Bose gas confined inside a harmonic trap at finite temperature. The theory treats the motions of the condensate…
