We develop a percolation model motivated by recent experimental studies of gels with active network remodeling by molecular motors. This remodeling was found to lead to a critical state reminiscent of random percolation (RP), but with a cluster distribution inconsistent with RP. Our model not only can account for these experiments, but also exhibits an unusual type of mixed phase transition: We find that the transition is characterized by signatures of criticality, but with a discontinuity in the order parameter.
我们基于分子马达对凝胶进行主动网络重塑的近期实验研究，开发了一种渗流模型。研究发现，这种重塑会导致一种类似于随机渗流（RP）的临界状态，但团簇分布与RP不一致。我们的模型不仅可以解释这些实验，还展现出一种不同寻常的混合相变类型：我们发现这种相变具有临界性特征，但序参量存在不连续性。
