Dynamical localization for two-level systems periodically driven

  • 1. Department of Mathematics, University of Modena and Reggio Emilia, Via Campi 213/B, 41100, Modena (Italy)

Description

Here, we consider a two-level system driven by an external periodic field. We show that the coherent destruction of tunnelling, as proved by Grossmann and co-workers (1991 Phys. Rev. Lett. 67 516; 1992 Europhys. Lett. 18 571) in the case of a monochromatic field, also appears for any periodic driving field given by an even regular function with zero mean value and satisfying a technical condition on the zeros of this function.
