Absolute Transverse Mobility and Ratchet Effect on Periodic 2D Symmetric Substrates | | C. Reichhardt

24 Dec 2002 | | Journal: | Phys. Rev. E 68, 046102 (2003) | | Subject: | Statistical Mechanics; Soft Condensed Matter | cond-mat.stat-mech cond-mat.soft | | Abstract: | We present a simple model of an overdamped particle moving on a two dimensional symmetric periodic substrate with a dc drive in the longitudinal direction and additional ac drives in both the longitudinal and transverse directions. For certain regimes we find that a finite longitudinal dc force produces a net dc response only in the transverse direction, which we term absolute transverse mobility. Additionally we find regimes exhibiting a ratchet effect in the absence of an applied dc drive. | | Source: | arXiv, cond-mat/0212576 | | Services: | Forum | Review | PDF | Favorites | |
