本文提出了一种数值方法，用于蒙特卡罗模拟跳跃噪声驱动的Landau-Lifshitz动力学，并通过数值例子加以说明。这种技术的两个核心要素是“中点”有限差分法集成的确定性岁差和“自散射”，这导致在时间均匀化的跳跃噪声过程。
A numerical technique for Monte Carlo simulations of Landau-Lifshitz dynamics driven by a jump-noise process is presented and illustrated by numerical examples. The two central elements of this technique are the “midpoint” finite-difference scheme for integration of deterministic precessions and “self-scattering” which results in time-homogenization of a jump-noise process.
