论文摘要
我们在GAAS双量子点系统中执行浮部光谱，该系统耦合到高阻力超导谐振器。通过在双重共振条件下应用微波诱导的连续段落，我们观察到了新型的Landau-Zener-Stückelberg-Majorana干扰模式，这些干扰模式源于腔液的消耗所改变的空腔辅助干扰模式。我们的实验结果揭示了强大驱动的两级系统的固定状态行为，并且与基于我们的理论模型的模拟一致。这项研究为在存在强驾驶的情况下研究了Floquet状态的动态提供了一个绝佳的平台。
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.
