摘要

我们发现双色高谐波光谱可以揭示有限尺寸和边缘态诱导的动态电子相关效应在普通纳米结构带隙材料。与大块样品的响应相比，我们通过利用这些超快多电子动力学的功率，证明了在宽频率范围内产生的信号效率的显著相关诱导增加。

Edge-state-induced correlation effects in two-color pump-probe high-order harmonic generation

We show that two-color high-harmonic spectroscopy can reveal finite-size and edge-state-induced dynamic electron correlation effects in a generic nanostructured band-gap material. Compared to the response of a bulk sample, we demonstrate a significant correlation-induced increase in the efficiency of the generated signal over a wide range of frequencies by harnessing the power of these ultrafast many-electron dynamics.
