欠阻尼量子棘轮
Underdamped quantum ratchets
摘要：
我们研究了弱耗散影响下的量子棘轮效应，我们在Floquet-Markov主方程方法内处理。当所有相关的对称性都被破坏时，棘轮电流就会出现。利用时间反演对称驱动，我们预测了一个纯粹的耗散诱导的量子棘轮电流。这种定向量子输运是由非输运Floquet态的浴诱导叠加引起的。
英文摘要：
We investigate the quantum ratchet effect under the influence of weak dissipation which we treat within a Floquet-Markov master equation approach. A ratchet current emerges when all relevant symmetries are violated. Using time-reversal symmetric driving we predict a purely dissipation-induced quantum ratchet current. This directed quantum transport results from bath-induced superpositions of non-transporting Floquet states.
