Mapping onto Electrodynamics of a Two-dimensional Bose-Einstein Condensate

A thorough mapping between the hydrodynamics of a two-dimensional Bose-Einstein condensate and the nonrelativistic classical electrodynamics of a charged material medium is proposed. This is shown to provide a very useful frame to discuss several features of vortex dynamics. Two important local conservation theorems of energy and angular momentum are derived and further applications are summarized.
