对于处于和非平衡状态的经典布朗系统,我们扩展了Schmidt和Brader (2013 J. Chem.)的幂函数形式主义。物理学,138 214101)到不同类型粒子的混合物。我们应用该框架来开发一个精确的动态测试粒子理论,用于自我和van Hove函数的不同部分,它们表征标记和集体粒子运动。诱导非马尔可夫动力学的记忆函数与过量(超理想)自由功率耗散泛函的泛函导数有关。该方法为动态对相关函数的非平衡Ornstein-Zernike关系提供了一种替代方法。
For classical Brownian systems both in and out of equilibrium we extend the power functional formalism of Schmidt and Brader (2013 J. Chem. Phys. 138 214101) to mixtures of different types of particles. We apply the framework to develop an exact dynamical test particle theory for the self and distinct parts of the van Hove function, which characterize tagged and collective particle motion. The memory functions that induce non-Markovian dynamics are related to functional derivatives of the excess (over ideal) free power dissipation functional. The method offers an alternative to the recently found nonequilibrium Ornstein–Zernike relation for dynamic pair correlation functions.
