基于幂函数理论[M.Schmidt和J. M.Brader,J.Chem],我们发展了一个描述布朗系统中非平衡稳态之间的相共存的一般理论。太棒了。138,214101(2013年)]。我们将该框架应用于主动软球游泳者的流液相分离的特殊情况。该理论的中心目标,耗散自由功率,通过计算机模拟计算,并与一个简单的解析近似进行了比较。该理论很好地描述了模拟数据,并预测了由于避免了耗散团簇而导致的动力诱导相分离。
We develop a general theory for describing phase coexistence between nonequilibrium steady states in Brownian systems, based on power functional theory [M. Schmidt and J. M. Brader, J. Chem. Phys. 138, 214101 (2013)]. We apply the framework to the special case of fluid-fluid phase separation of active soft sphere swimmers. The central object of the theory, the dissipated free power, is calculated via computer simulations and compared to a simple analytical approximation. The theory describes well the simulation data and predicts motility-induced phase separation due to avoidance of dissipative clusters.
