波函数的时间演化为量子理论中的波包动力学提供了一个美丽的见解。在这项工作中，我们研究了具有移动壁的量子阱内粒子的波包动力学。由于一壁随时间移动，该系统的本征波函数和本征能量是时间相关的，这使得该系统中波包的时间演化比具有两个静态壁的量子阱中的情况变得更加复杂和有趣。结果表明，当墙体运动速度很慢时，波包的部分复活现象存在，但一次复活时波包的完全复活现象消失了……
The time evolution of the wave function provides a beautiful insight into the wave packet dynamics in the quantum theory. In this work, we study the wave packet dynamics of a particle inside a quantum well with one moving wall. Since one wall is moving with time, the eigen wave function and eigen energy of this system are time-dependent, which makes the time evolution of the wave packet in this system become much more complicated and interesting compared to the case in a quantum well with two static walls. It is shown when the wall is moving very slowly, fractional revival phenomenon of wave packet is shown to exist, but the full revival of the wave packet at one revival time is disappeared…
