我们研究沿通道的两个储层之间的随机粒子传输，其中粒子通过行波势逆向泵送。结果表明，当考虑粒子之间的排斥相互作用时，通道内会发生周期平均密度或电流的相变。这些转变反映了已知的不对称简单排除过程。我们认为它们的出现是开放系统中运行的布朗电机的普遍特征。
We study stochastic particle transport between two reservoirs along a channel, where the particles are pumped against a bias by a traveling wave potential. It is shown that phase transitions of period-averaged densities or currents occur inside the channel when exclusion interactions between the particles are taken into account. These transitions reflect those known for the asymmetric simple exclusion process. We argue that their occurrence is a generic feature of Brownian motors operating in open systems.
