论文摘要
自由量子高斯波包的从左到右运动可以伴随着概率密度的左转流，这是Villanueva最近研究的效果[am。 J. Phys。 88，325（2020）]。使用波数据包的Wigner表示，我们分析了相空间中的效果，并证明其物理起源植根于经典力学。
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.
