摘要翻译：
我们研究了有限尺寸效应对一维零程过程动力学的影响，该过程显示了从低密度无序相到高密度凝聚相的相变。稳态下的电流波动在两个阶段表现出明显的差异。在无序阶段，积分电流的方差在时间上表现出阻尼振荡，这是由于环的波动作为一种耗散的运动波围绕着环的运动。在凝结相中，这种波不能通过凝析油传播，其动力学受凝析油长时间在场地间的迁移控制。

英文摘要：
  We study finite-size effects on the dynamics of a one-dimensional zero-range process which shows a phase transition from a low-density disordered phase to a high-density condensed phase. The current fluctuations in the steady state show striking differences in the two phases. In the disordered phase, the variance of the integrated current shows damped oscillations in time due to the motion of fluctuations around the ring as a dissipating kinematic wave. In the condensed phase, this wave cannot propagate through the condensate, and the dynamics is dominated by the long-time relocation of the condensate from site to site.
