Measurement of the Temperature Dependence of the Casimir-Polder Force
J. M. Obrecht, R. J. Wild, M. Antezza +3
We report on the first measurement of a temperature dependence of the Casimir-Polder force. This measurement was obtained by positioning a nearly pure 87-Rb Bose-Einstein condensat…
Normal state of a polarized Fermi gas at unitarity
C. Lobo, A. Recati, S. Giorgini +1
We study the Fermi gas at unitarity and at T=0 by assuming that, at high polarizations, it is a normal Fermi liquid composed of weakly interacting quasiparticles associated with th…
Quantum fluctuations and collective oscillations of a Bose-Einstein condensate in a 2D optical lattice
G. Orso, C. Menotti, S. Stringari
We use Bogoliubov theory to calculate the beyond mean field correction to the equation of state of a weakly interacting Bose gas in the presence of a tight 2D optical lattice. We s…
Casimir-Lifshitz force out of thermal equilibrium and asymptotic non-additivity
Mauro Antezza, Lev P. Pitaevskii, Sandro Stringari +1
We investigate the force acting between two parallel plates held at different temperatures. The force reproduces, as limiting cases, the well known Casimir-Lifshitz surface-surface…
One-dimensional description of a Bose-Einstein condensate in a rotating closed-loop waveguide
S. Schwartz, M. Cozzini, C. Menotti +3
We propose a general procedure for reducing the three-dimensional Schrodinger equation for atoms moving along a strongly confining atomic waveguide to an effective one-dimensional…
Pair correlations of an expanding superfluid Fermi gas
C. Lobo, I. Carusotto, S. Giorgini +2
The pair correlation function of an expanding gas is investigated with an emphasis on the BEC-BCS crossover of a superfluid Fermi gas at zero temperature. At unitarity quantum Mont…
