SUMMARY:GRK Kolloquium:Introduction to Floquet theory
DESCRIPTION:Location: RUN auditorium \n\n\n\nHow to characterize properties of a quantum system subject to an intense time-periodic drive? We shall address this question within the framework of Floquet theory. According to the Floquet theorem\, the solutions of the time-dependent Schrödinger equation display a quasi-stationary evolution\, governed by quasi-energies\, and a periodic part. Working in the Sambe space\, it is possible to evaluate both the so-called quasi-energy spectrum and the Floquet functions without resorting to perturbation theory in the strength of the time-periodic drive or other commonly used approximations. Noticeably\, the quasi-energy spectrum can be qualitatively different from the one of the undriven Hamiltonian\, opening pathways to manipulate properties of quantum systems by a time-periodic drive. These concepts will be illustrated on the example of a strongly driven two-level system. \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nProf. Dr. Milena GrifoniUniversity of Regensburg
