28 Oct 1997 | | Journal: | Phys. Rev. B 57, 2720 (1998) | | Subject: | Superconductivity; Mesoscopic Systems and Quantum Hall Effect | cond-mat.supr-con cond-mat.mes-hall | | Abstract: | We consider a two-dimensional array of ultra-small superconducting grains, weakly coupled by Josephson junctions with large charging energy. We start from an effective action based on a microscopic tunneling Hamiltonian, which includes quasiparticle degrees of freedom, and study the resulting dissipative dynamics of quantum vortices. The equation of motion for a single vortex is deduced, and compared with a commonly adopted phenomenological model. | | Source: | arXiv, cond-mat/9710293 | | Services: | Forum | Review | PDF | Favorites | |
