实时路径积分散射
Scattering with real-time path integrals
摘要：
利用实时路径积分计算了短程高斯势散射的锐动量跃迁矩阵元。该计算是基于一个新的解释的路径积分作为一个潜在的功能相对于一个复杂的概率分布在圆柱体上的路径集的期望的数值实现。该方法与酉传递矩阵计算密切相关。
英文摘要：
Sharp-momentum transition matrix elements for scattering from a short-range Gaussian potential are computed using a real-time path integral. The computation is based on a numerical implementation of a new interpretation of the path integral as the expectation of a potential functional with respect to a complex probability distribution on cylinder sets of paths. The method is closely related to a unitary transfer matrix computation.
