We study the interplay of strong correlations and coherent driving by considering the strong coupling Kondo model driven by a time-periodic bias voltage. Combining a recent nonequilibrium renormalization group method with Floquet theory, we find that by the coherent dressing of the driving field side replicas of the Kondo resonance emerge in the conductance, which are not completely washed out by the decoherence induced by the driving. We show that to accurately capture the interplay of driving and strong correlations one needs to go beyond simple phenomenological pictures, which underestimate decoherence, or adiabatic approximations, highlighting the relevance of non-Markovian memory effects. Within our method the differential conductance shows good quantitative agreement with experimental data in the full crossover regime from weak to strong driving. We analyze memory effects in detail based on the response to short voltage pulses.

周期性驱动的 Kondo 模型的 Floquet 重整化组方法

我们通过考虑由时间周期偏置电压驱动的强耦合 Kondo 模型来研究强相关性和相干驱动的相互作用。将最近的非平衡重整化群方法与 Floquet 理论相结合，我们发现通过驱动场侧的相干修饰，Kondo 共振的复制品出现在电导中，这些复制品并没有被驱动引起的退相干完全冲刷掉。我们表明，要准确捕捉驾驶和强相关性的相互作用，需要超越简单的现象学图片，这些图片低估了退相干或绝热近似，突出了非马尔可夫记忆效应的相关性。在我们的方法中，微分电导与从弱驱动到强驱动的完全交叉状态下的实验数据显示出良好的定量一致性。我们根据对短电压脉冲的响应详细分析记忆效应。
