Phase locking effect and current reversals in deterministic underdamped ratchets
We study the transport properties (currents) of deterministic underdamped ratchets in terms of phase locking dynamics. The occurrence of reverse currents is interpreted in terms of different stability properties of the periodic rotating orbits and is shown to exist also in the absence of bifurcations from chaos to periodic motion. We briefly discuss the effects of noise on this phase locked dynamics.
