Abstract

An Ising chain with Kawasaki spin-exchange dynamics in contact with a heat bath with temporal periodic variation between two temperatures is considered. This environment prohibits the system from attaining thermal equilibrium. We demonstrate here via Monte Carlo simulations that such a case exhibits a Brownian motor type collective transport. This confirms our hypothesis that a cycle of cluster and dispersion of domains with fine-tuned parameters, in effect, results into spin transport.
