摘要

原子薄过渡金属二硫化物(TMDCs)的激子物理对于基础物理研究和前景应用具有重要意义。然而，激子物理的实验探索，包括激子相干动力学、激子多体相互作用及其光学性质，面临着空间异质性和复杂的多体效应等因素的挑战。从这个角度来看，我们详细阐述了光学二维相干光谱(2DCS)如何成为解决挑战的有效工具，并概述了在即将到来的2DCS技术和新材料的进步实验中获得更深入了解激子物理的潜在方向。

Optical two-dimensional coherent spectroscopy of excitons in transition-metal dichalcogenides

Exciton physics in atomically thin transition-metal dichalcogenides (TMDCs) holds paramount importance for fundamental physics research and prospective applications. However, the experimental exploration of exciton physics, including excitonic coherence dynamics, exciton many-body interactions, and their optical properties, faces challenges stemming from factors such as spatial heterogeneity and intricate many-body effects. In this perspective, we elaborate upon how optical two-dimensional coherent spectroscopy (2DCS) emerges as an effective tool to tackle the challenges, and outline potential directions for gaining deeper insights into exciton physics in forthcoming experiments with the advancements in 2DCS techniques and new materials.
