Hydrodynamics of Superfluid Bose Gases in an Optical Lattice at Finite Temperatures
Satoru Konabe, Tetsuro Nikuni
Starting from an effective action for the order parameter field, we derive a coupled set of generalized hydrodynamic equations for a Bose condensate in an optical lattice at finite…

Landau damping: instability mechanism of superfluid Bose gases moving in optical lattices
Kiyohito Iigaya, Satoru Konabe, Ippei Danshita +1
We investigate Landau damping of Bogoliubov excitations in a dilute Bose gas moving in an optical lattice at finite temperatures. Using a 1D tight-binding model, we explicitly obta…
