论文摘要
超快光脉冲是控制量子材料并触发新型光诱导相变的越来越重要的工具。了解这些动态现象需要对旋转，电荷和轨道自由度敏感的探针。时间分辨的谐振非弹性X射线散射（TRRIXS）是一种新兴的光谱法，通过提供对光激发固体的有限摩托车波动光谱的前所未有的访问，可以响应这种需求。从这个角度来看，我们简要回顾了有关凝结物质系统以及最新理论进步的最先进的Trrixs实验。然后，我们在量子问题的光控制背景下描述未来的研究机会。
Ultrafast optical pulses are an increasingly important tool for controlling quantum materials and triggering novel photo-induced phase transitions. Understanding these dynamic phenomena requires a probe sensitive to spin, charge, and orbital degrees of freedom. Time-resolved resonant inelastic X-ray scattering (trRIXS) is an emerging spectroscopic method, which responds to this need by providing unprecedented access to the finite-momentum fluctuation spectrum of photoexcited solids. In this Perspective, we briefly review state-of-the-art trRIXS experiments on condensed matter systems, as well as recent theoretical advances. We then describe future research opportunities in the context of light control of quantum matter.
