Superfluid flow past an obstacle in annular Bose–Einstein condensates

We investigate the flow of a one-dimensional nonlinear Schroedinger model with periodic boundary conditions past an obstacle, motivated by recent experiments with Bose-Einstein condensates in ring traps. Above certain rotation velocities, localized solutions with a nontrivial phase profile appear. I...
