BROWNIAN MOTORS BASED ON ELECTRIC DIPOLE INTERACTION

Brownian motors based on electric dipoles interaction are studied. Directed motion is induced by the transitions of the electric dipoles potentials between two states. The stationary probability current of the Brownian motors is evaluated. The current is sensitive to temperature and the values of the transition rates between two states. There are optimal values of temperature and the transition rates for the current, and for a suitable choice of the transition rates the current can be reversed.
