相对运动的分子之间的色散力，耦合到不同温度的浴槽，或激发态，使用格林函数Liouville空间展开计算，将著名的McLachlan响应理论扩展到非线性状态。我们的动力学理论适用于可能处于任何初始非平衡状态和受任意时变耦合影响的系统。与吸引的平衡力相比，非平衡力可能是吸引或排斥的，表现出化学特定的共振，更强，并且可能是非保守的（具有正或负耗散）。
Dispersion forces between molecules that are in relative motion, coupled to baths at different temperatures, or in excited states, are calculated using a Green function Liouville space expansion that extends the celebrated McLachlan response theory to the nonlinear regime. Our dynamical theory is applicable to systems that may be in any initial nonequilibrium state and that are subject to an arbitrary time-dependent coupling. In contrast to equilibrium forces which are attractive, nonequilibrium forces may be attractive or repulsive, exhibit chemically specific resonances, are far stronger, and may be nonconservative (with either positive or negative dissipation).
