Abstract
We derive the exact equation of motion for a vortex in two- and three- dimensional nonrelativistic systems governed by the Ginzburg-Landau eq uation with complex coefficients. The velocity is given in terms of lo cal gradients of the magnitude and phase of the complex field and is e xact also for arbitrarily small intervortex distances. The results for vortices in a superfluid or a superconductor are recovered.
