Interaction-induced current-reversals in driven lattices

Blog Article

Long-range interactions are shown to cause, as time evolves, consecutive reversals of directed read more currents for dilute ensembles of particles in driven lattices.These current reversals are based on a general mechanism that leads to an interaction-induced accumulation of particles in the regular regions of the underlying single-particle phase space and to a synchronized single-particle motion as well as enhanced efficiency of Hamiltonian ratchets.Suggestions for experimental implementations using ionized mesoscopic clusters in micromechanical lattices or dipolarly interacting colloidal particles in ac-driven optical fleshlight automatique lattices are provided.
