  • 摘要

    提供一种新的解法，经过求解微分方程很简单地得到了与殷雯(物理学报52 1862)同样的结果.殷文通过精确求解含时量子体系，研究了在周期耦合驱动下电子在两量子阱中的受迫振荡，不仅得到了一般情况下的振荡公式，而且特别讨论了在ω=0情况下电子布居数的演化行为.

     

    Abstract

    The oscillation of electron between two quantum wells has been studied by exactly solving the time-dependent Schrdinger equation(Acta Phys. Sin. 52 1862). The oscillation behaviour for a general case was given and the case for ω=0 was specially discussed. In this paper, we obtained the same solution more simply for the ω＝0 case using a new method.
