布朗泵中的相变

Phase Transitions in Brownian Pumps

Marcel Dierl, Wolfgang Dieterich, Mario Einax, Philipp Maass

摘要:

我们研究了两个水库之间的随机粒子输运沿一个通道,其中的粒子被泵对偏置的行波潜力。它表明,周期平均密度或电流的相变发生在通道内的粒子之间的排斥相互作用时,考虑。这些转变反映了那些已知的不对称简单排斥过程(ASEP)。我们认为,它们的发生是一个通用的功能布朗电机在开放系统中运行。

英文摘要:

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 (ASEP). We argue that their occurrence is a generic feature of Brownian motors operating in open systems.
