Abstract
We consider a two-dimensional array of ultrasmall superconducting grai ns, weakly coupled by Josephson junctions with large charging energy. We start from an effective action based on a microscopic tunneling Ham iltonian, which includes quasiparticle degrees of freedom, and study t he resulting dissipative dynamics of quantum vortices. The equation of motion for a single vortex is deduced, and compared with a commonly a dopted phenomenological model.
