Abstract

The dynamics of an array of linearly coupled one-dimensional Bose-Einstein condensates is studied by a mean-field method, which reveals that the coupling leads to the system's evolution into a range of phase textures including Josephson vortices, vortex dipoles, half-dark solitons, and arrays of the like.
