Directed transport and Floquet analysis for a periodically kicked wavepacket at a quantum resonance
arXiv:nlin/0602020 · doi:10.1103/PhysRevE.74.016212
Abstract
The dynamics of a kicked quantum mechanical wavepacket 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.
