一维概率密度的渐近性质
Asymptotic behaviour of the probability density in one dimension
摘要:
我们证明了在一维空间中自由运动的量子态的几率密度可以衰减得比1/t快。逆二次和三次相关性说明了解析可解的例子。衰减速度超过1/t允许存在停留时间和延迟时间。
英文摘要:
We demonstrate that the probability density of a quantum state moving freely in one dimension may decay faster than 1/t. Inverse quadratic and cubic dependences are illustrated with analytically solvable examples. Decays faster than 1/t allow the existence of dwell times and delay times.
