We examine the effect of spatial correlations on the phenomenon of real-space condensation in driven mass-transport systems. We suggest that in a broad class of models with a spatially correlated steady state, the condensate drifts with a nonvanishing velocity. We present a robust mechanism leading to this condensate drift. This is done within the framework of a generalized zero-range process (ZRP) in which, unlike the usual ZRP, the steady state is not a product measure. The validity of the mechanism in other mass-transport models is discussed.
我们研究了空间相关性对驱动质量传输系统中实空间凝聚现象的影响。我们认为，在一大类具有空间相关稳态的模型中，凝聚体以非零速度漂移。我们提出了一种导致这种凝聚体漂移的稳健机制。这是在广义零程过程（ZRP）的框架内完成的，与通常的ZRP不同，其稳态不是乘积测度。我们还讨论了该机制在其他质量传输模型中的有效性。
