Abstract
The electron dynamics in a double quantum well under strong AC electric field and tilted magnetic field is studied using a non-perturbative Floquet approach. For B∥ = 0, the quasienergy spectra show two types of crossings: those related to different Landau levels (LL), and those due to dynamic localization (DL). We find that the system exhibits DL at the same values of the AC field suggesting a hidden dynamical symmetry identified with different parity operations. We analyze also the time evolution of the system, monitoring the elapsed time to return to a given well, and find a complex behavior which is studied in detail. © 2003 Elsevier Science B.V.
