论文摘要
在一维随机步行中，即使在存在偏见的情况下，每个方向转变的等待时间都是相同的，这是由于微观可逆性的。我们研究了在两个车道的晶格上随机步行中向前/向后转变时间的对称破坏。我们发现，根据晶格的净电流，过渡时间可以更快，并且仅在平衡下恢复对称性。我们的分析表明，向前/向后的过渡时间不对称可以用作远离系统均衡的衡量标准。
In one-dimensional random walks, the waiting time for each direction transitions is the same, even in the presence of bias, as a consequence of the microscopic-reversibility. We study the symmetry breaking of forward/ backward transition times in a random walk on a lattice of two lanes. We find that either transition times can be faster depending on the lattice's net current, and the symmetry is recovered only at equilibrium. Our analysis suggests that the forward/ backward transition times' asymmetry can be used as a measure of deviation from the equilibrium of the system.
