Harmonic generation and Dynamic localization in a driven two-level system, non-perturbative results using the Floquet-Green operator — •Dario F. Martinez — Max-Planck-Institut für Physik komplexer System, Nöthnitzer Str. 38, 01187 Dresden

A general solution for the quasienergies and eigenstates of this system is obtained using the Floquet-Green formalism. From the time-evolution operator we study the general features of the dynamic localization of the system and also obtain general non-perturbative expressions for the time-dependent dipole moment. We discuss the different kinds of harmonics generated by the external driving and their dependence on the initial state and on the different parameters of the problem.
