Critical velocity of superfluid flow through single barrier and periodic potentials
Gentaro Watanabe, F. Dalfovo, F. Piazza +2
We investigate the problem of an ultracold atomic gas in the superfluid phase flowing in the presence of a potential barrier or a periodic potential. We use a hydrodynamic scheme i…

Van der Waals forces and spatial dispersion
L. P. Pitaevskii
A version of the Green's functions theory of the Van der Waals forces which can be conveniently used in the presence of spatial dispersion is presented. The theory is based on the…

First and second sound in a strongly interacting Fermi gas
E. Taylor, H. Hu, X. -J. Liu +3
Using a variational approach, we solve the equations of two-fluid hydrodynamics for a uniform and trapped Fermi gas at unitarity. In the uniform case, we find that the first and se…
