Abstract
A quasienergy structure of a dynamic Wannier-Stark ladder (DWSL) that is driven by a pulse train with periodic repetition is analyzed. Here, novel properties on coherent control realized by means of tuning a combination of laser parameters are revealed. In particular, we report a striking property that interminiband interactions due to both static and dynamic Zener tunnelings are completely removed from the DWSL by utilizing the periodic pulse train with either square or full-cycle saw-toothed unit-pulse-shape in a temporal domain, regardless of magnitude of Dc- and Ac-electric fields exerted on the original superlattices.
