Ultrafast Dynamics of Quantum Materials

杨小组将建立和开发先进的光学光谱，以探测两类量子材料的物理性质：二维(2D)原子薄的过渡金属二卤化物和拓扑Weyl半金属。这些新兴的材料家族目前引起了人们的极大兴趣，因为它们不仅为探索二维纳米结构和拓扑量子物质中的新物理提供了肥沃的平台，而且在各种光电子学、量子信息和清洁能源应用方面也有着巨大的前景。这些研究将提供对这些量子材料的内在物理的直接洞察，并将为未来的应用迈出重要的一步。

The Yang group will build and develop advanced optical spectroscopies to probe the physical properties in two classes of quantum materials: two-dimensional (2D) atomically-thin transition-metal dichalcogenides, and topological Weyl semimetals. These emerging materials families are currently of great interest, because they not only provide fertile platforms to explore new physics in 2D nanostructures and topological quantum matter, but also hold great promise for a variety of optoelectronics, quantum information and clean energy applications. The studies will provide direct insight into the intrinsic physics in these quantum materials and will make essential steps towards future applications.
