We develop a novel numerical method for solving the Wigner equation which does not rely upon evaluation of the Wigner kernel and utilizes quantum trajectories. This method is a generalization of the effective potential approach widely used in semiconductor TCAD tools while also solving the full Wigner equation. The method’s accuracy is demonstrated with several standard examples.

波包相空间量子蒙特卡罗方法

我们开发了一种新型的求解维格纳方程的数值方法，该方法不依赖于维格纳核的评估，而是利用了量子轨迹。该方法是在半导体T​​CAD工具中广泛使用的有效电势方法的概括，同时还可以求解完整的Wigner方程。通过几个标准示例证明了该方法的准确性。
