论文摘要
我们对多种生物学过程的理解不仅是必不可少的，而且还为发现新颖的物理学提供了肥沃的基础。在活动系统中已经证明了平衡系统不可能的许多新兴特性。这些紧急的特征包括运动诱导的相位分离，二维的长度有序（集体运动）相位以及订单diSorder相共存（带和反向循环态度）。在这里，我们将这些多样化的相变和相共存统一为基于活动流体的通用流体动力方程的单个公式。我们还揭示了一个新颖的共存共存阶段和一个假定的新颖关键点。
Active matter is not only indispensable to our understanding of diverse biological processes, but also provides a fertile ground for discovering novel physics. Many emergent properties impossible for equilibrium systems have been demonstrated in active systems. These emergent features include motility-induced phase separation, long-ranged ordered (collective motion) phase in two dimensions, and order-disorder phase co-existences (banding and reverse-banding regimes). Here, we unify these diverse phase transitions and phase co-existences into a single formulation based on generic hydrodynamic equations for active fluids. We also reveal a novel co-moving co-existence phase and a putative novel critical point.
