Damping of Bogoliubov Excitations in Optical Lattices
S. Tsuchiya, A. Griffin
Extending recent work to finite temperatures, we calculate the Landau damping of a Bogoliubov excitation in an optical lattice, due to coupling to a thermal cloud of such excitatio…

Superfluidity and collective modes in a uniform gas of Fermi atoms with a Feshbach resonance
Y. Ohashi, A. Griffin
We investigate strong-coupling superfluidity in a uniform gas of Fermi atoms attractively interacting via quasi-molecular bosons associated with a Feshbach resonance. This interact…
