| Keywords: | Superconductivity Statistical Mechanics |
| Publisher: | Institute of Physics Publishing Deutsche Physikalische Gesellschaft |
| Description: | 13 pages, 7 figures Competition between the vortex lattice and a lattice of asymmetric artificial defects is shown to play a crucial role in ratchet experiments in superconducting films. We present a novel and collective mechanism for current reversal based on a reconfiguration of the vortex lattice. In contrast to previous models of vortex current reversal, the mechanism is based on the global response of the vortex lattice to external forces. |
