Ratchet behavior in nonlinear Klein-Gordon systems with point-like inhomogeneities
Luis Morales-Molina, Franz G. Mertens, Angel Sanchez
We investigate the ratchet dynamics of nonlinear Klein-Gordon kinks in a periodic, asymmetric lattice of point-like inhomogeneities. We explain the underlying rectification mechani…

Ratchets in homogeneous extended systems: internal modes and the role of noise
Angel Sanchez, Luis Morales-Molina, Franz G. Mertens +3
We revisit the issue of directed motion induced by zero average forces in extended systems driven by ac forces. It has been shown recently that a directed energy current appears if…
