摘要

摘要: 压力不仅显著改变物质内原子间距，还可以调制电子结构，诱导出新奇物相，获得独特物性。研究高压下物质原子、电子结构的演化是物质科学的关键环节。本文介绍三种前沿X射线散射谱学方法——X射线拉曼散射(XRS)、核共振振动能谱(NRVS)、共振非弹性X射线散射(RIXS)。三类散射谱学方法能够提供电子结构、声子态密度、轨道及自旋激发等关键信息，在高压领域中有重要的应用价值。第四代同步辐射光源HEPS上已建成高能量分辨谱学线站，专注于此类散射谱学手段，将为国内外高压前沿研究提供关键利器。

Abstract: Pressure can not only alter interatomic distances within materials, but also manipulate electronic structure to induce exotic phases emerging with unique physical properties. Uncovering the evolution of atomic and electronic structures of matters under high pressure is of utmost importance in physical sciences. This article introduces three state-of-the-art X-ray scattering spectroscopies, namely, X-ray Raman scattering (XRS), Nuclear Resonant Vibrational scattering (NRVS), and Resonant Inelastic X-ray Scattering (RIXS). These scattering spectroscopies can be explored to provide key information including electronic structures, phonon density of states, orbital and spin excitations, etc, which are of great value in high-pressure studies. At the 4th generation High Energy Photon Source (HEPS), the hard X-ray high energy resolution spectroscopy beamline is constructed and dedicated to such scattering spectroscopies. It is envisaged the suite of scattering spectroscopies will help the advancement of high-pressure researches world widely.
