We derive a hierarchy of stochastic evolution equations for pure states (quantum trajectories) for open quantum system dynamics with non-Markovian structured environments. This hierarchy of pure states (HOPS) is generally applicable and provides the exact reduced density operator as an ensemble average over normalized states. The corresponding nonlinear equations are presented. We demonstrate that HOPS provides an efficient theoretical tool and apply it to the spin-boson model, the calculation of absorption spectra of molecular aggregates, and energy transfer in a photosynthetic pigment-protein complex.
我们推导了具有非马尔可夫结构化环境的开放量子系统动力学中纯态（量子轨迹）的随机演化方程层次结构。这种纯态层次结构（HOPS）具有普遍适用性，并通过对归一化态的系综平均给出精确的约化密度算符。给出了相应的非线性方程。我们证明HOPS提供了一种有效的理论工具，并将其应用于自旋 - 玻色子模型、分子聚集体吸收光谱的计算以及光合色素 - 蛋白质复合物中的能量转移。
