SUMMARY:RTG Seminar: Cavity optomechanics in the few photon regime using nanowires and photonic crystals
DESCRIPTION:Institut Néel; Université Grenoble-Alpes \n\n\n\n \n\n\n\nHuge developments have been done in the field of cavity optomechanics\, essentially by using large photon number to enhance the weak optomechanical interaction. Thus\, in our work\, we aim at approaching the single photon regime\, where a single photon in the cavity mode can have an appreciable impact on the nanowire\, which requires g_0>Ωm. This requires operating with ultrasensitive force sensors with small mode volume microcavities\, which enhance the electromagnetic field per photon. To do so\, we employ photonic crystal (PhC) cavities fabricated at C2N and suspended SiC nanowires\, whose vibrating extremity is inserted into the evanescent cavity field. The nanowire being smaller than the wavelength\, this allows us to image this confined light field\, and to map the optomechanical coupling strength. Then\, equiped with a probe laser and an external driving electrode\, we measure and map the optomechanical force experienced by the nanowire. Our results are compared to numerical simulations\, which also allows to understand the proximity forces arising when approaching the nanostructures. \n\n\n\n\n\n\n\n\n\n\n\n\n\nVenue: RUN 0.35

SUMMARY:RTG 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
