Current reversals in a rocking ratchet: The frequency domain
Abstract
Motivated by recent work [D. Cubero , Phys. Rev. EPLEEE81539375510.1103/PhysRevE.82.041116 82, 041116 (2010)], we examine the mechanisms which determine current reversals in rocking ratchets as observed when varying the frequency of the drive. We found that a class of these current reversals in the frequency domain is precisely determined by dissipationinduced symmetry breaking. Our experimental and theoretical work thus extends and generalizes the previously identified relationship between dynamical and symmetrybreaking mechanisms in the generation of current reversals.
