The left-to-right motion of a free quantum Gaussian wave packet can be accompanied by the right-to-left flow of the probability density, the effect recently studied by Villanueva [Am. J. Phys. 88, 325 (2020)]. Using the Wigner representation of the wave packet, we analyze the effect in phase space, and demonstrate that its physical origin is rooted in classical mechanics.

评论“概率的负向流动”[Am。J.物理。88, 325–333 (2020)]

自由量子高斯波包的从左到右运动可以伴随概率密度从右到左的流动,维拉纽瓦最近研究了这种效应 [Am. J.物理。88, 325 (2020)]。使用波包的 Wigner 表示,我们分析了相空间中的效应,并证明其物理起源植根于经典力学。
