Current reversals in a rocking ratchet: The frequency domain
Current reversals in a rocking ratchet: The frequency domain
Motivated by recent work [D. Cubero et al., Phys. Rev. E 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 …
