Abstract
We report a study of solutions of the defocusing nonlinear Schrodinger equa tion in a spatially periodic potential. The ground-state solution and the s teady flows of the system are studied analytically. Above a critical curren t, a steady state no longer exists and time-dependent solutions are generat ed, which are numerically simulated and described.
