Collective modes and superflow instabilities of strongly correlated Fermi superfluids
R. Ganesh, A. Paramekanti, A. A. Burkov
We study the superfluid phase of the one-band attractive Hubbard model of fermions as a prototype of a strongly correlated s-wave fermion superfluid on a lattice. We show that the…

Stability of Superflow for Ultracold Fermions in Optical Lattices
A. A. Burkov, Arun Paramekanti
Motivated by recent observations of superfluidity of ultracold fermions in optical lattices, we investigate the stability of superfluid flow of paired fermions in the lowest band o…
