- Abstract: 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-St\"uckelberg-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.

Multi-photon resonances to high-lying energy levels represent an unavoidable source of Floquet heating in strongly driven quantum systems.

We study the quantum Rabi model for a two-level system coupled to a quantized cavity mode under periodic modulation of the cavity-dipole coupling in the ultrastrong coupling regime, leading to rich Floquet states.
As an application of the theory, we show how purely mechanical driving can produce real photons, depending on the strength and frequency of the periodic coupling rate.
