Interplay of quantum mechanical barrier tunneling and thermally activated barrier crossing in a periodically rocked ratchet potential. At high temperatures, thermal noise dominates, resulting in an average preferential direction of motion to the right. At low temperatures, tunneling to the left dominates. |
