蒙特卡罗傅立叶路径积分方法进行了讨论,无论是相对于他们使用的平衡统计力学和化学动力学中使用。有人认为,这样的技术提供了一个实用的,直接的路线复杂的温度密度矩阵元素,实现最近的量子反应通量形式主义。应用到一维测试问题(Eckart屏障)进行了讨论。一个简单的(经典的)近似方案,涉及温度依赖的有效势也被认为是。
Monte Carlo Fourier path integral methods are discussed, both with respect to their use for equilibrium statistical mechanics and to their use in chemical dynamics. It is argued that such techniques offer a practical, direct route to complex temperature density matrix elements necessary to implement recent quantum reactive flux formalisms. Applications to a one‐dimensional test problem (the Eckart barrier) are discussed. A simple (classical) approximation scheme involving a temperature‐dependent effective potential is also considered.
