Ratchet Effects for Vortices in Superconductors with Periodic Pinning Arrays | C. Reichhardt

24 Oct 2003 | Journal: | Physica C 404, 302 (2004) | Subject: | Superconductivity | cond-mat.supr-con | Abstract: | Using numerical simulations we show that novel transport phenomena can occur for vortices moving in periodic pinning arrays when two external perpendicular ac drives are applied. In particular, we find a ratchet effect where the vortices can have a net dc drift even in the absence of a dc drive. This ratchet effect can occur for ac drives which create orbits that break one or more reflection symmetries. | Source: | arXiv, cond-mat/0310572 | Services: | Forum | Review | PDF | Favorites |
