Rectification and Flux Reversals for Vortices Interacting with Triangular Traps | C.J. Olson Reichhardt

2 Dec 2003 | Subject: | Superconductivity; Soft Condensed Matter | cond-mat.supr-con cond-mat.soft | Abstract: | We simulate vortices in superconductors interacting with two-dimensional arrays of triangular traps. We find that, upon application of an ac drive, a net dc flow can occur which shows current reversals with increasing ac drive amplitude for certain vortex densities, in agreement with recent experiments and theoretical predictions. We identify the vortex dynamics responsible for the different rectification regimes. We also predict the occurrence of a novel transverse rectification effect in which a dc flow appears that is transverse to the direction of the applied ac drive. | Source: | arXiv, cond-mat/0401016 | Services: | Forum | Review | PDF | Favorites |
