Floquet态是固体中一种周期性的强光驱动量子态，作为一种在超快时间尺度上相干可控的新态，一直受到人们的关注。一个重要的问题是实验证明新的电子性质的Floquet状态。一种技术是光散射光谱，它提供了一个重要的线索，澄清对称性和能量结构的状态，通过对称性分析的偏振选择规则。在这里，我们确定圆和线偏振选择规则的光散射在中红外驱动的Floquet系统在单层MoS2和Floquet状态的“动力学对称性”方面提供了全面的理解。
The Floquet state, which is a periodically and intensely light-driven quantum state in solids, has been attracting attention as a novel state that is coherently controllable on an ultrafast time scale. An important issue has been to demonstrate experimentally novel electronic properties in the Floquet state. One technique is light scattering spectroscopy, which offers an important clue to clarifying the symmetries and energy structures of the states through symmetry analysis of the polarization selection rules. Here, we determine circular and linear polarization selection rules of light scattering in a mid-infrared-driven Floquet system in monolayer MoS2and provide a comprehensive understanding in terms of the “dynamical symmetry” of the Floquet state.
