The dynamics of a kicked quantum mechanical wave packet at a quantum resonance is studied in the framework of Floquet analysis. It is seen how a directed current can be created out of a homogeneous initial state at certain resonances in an asymmetric potential. The almost periodic parameter dependence of the current is found to be connected with level crossings in the Floquet spectrum.
在弗洛凯分析的框架下研究了处于量子共振的受踢量子力学波包的动力学。可以看到,在不对称势中的某些共振情况下,如何从均匀的初始状态产生定向电流。发现电流几乎周期性的参数依赖性与弗洛凯谱中的能级交叉有关。
