Floquet state depletion in ac-driven circuit QEDMing-Bo Chen, Bao-Chuan Wang, Sigmund Kohler, Yuan Kang, Ting Lin, Si-Si Gu, Hai-Ou Li, Guang-Can Guo, Xuedong Hu, Hong-Wen Jiang, Gang Cao, and Guo-Ping GuoPhys. Rev. B 103, 205428 (2021) We perform Floquet spectroscopy in a GaAs double quantum dot system coupled to a high-impedance superconducting resonator. By applying microwave induced consecutive passages under a double resonance condition, we observe novel Landau-Zener-Stückelberg-Majorana interference patterns that stem from a cavity-assisted interference pattern modified by the depletion of the ground state. Our experimental results reveal the stationary state behavior of a strongly driven two-level system, and are consistent with the simulations based on our theoretical model. This study provides an excellent platform for investigating the dynamics of Floquet states in the presence of strong driving. arXiv:2011.03697 |
