论文摘要
固体中的非平衡电子动力学是从基本角度和技术观点既重要的主题。激光技术的最新发展使我们能够研究时域中的超快电子动力学。第一原理计算是分析这种复杂的电子动力学并阐明实验观察背后的物理学的强大工具。在本文中,我们通过修改其在最近的Attosend实验中的应用,回顾了固体中光诱导的电子动力学的第一原理计算的最新开发。电子动力学计算提供了固体的静态和瞬态光学特性的准确描述,并提供了对光引起的电子动力学的洞察力。此外,已经开发了非平衡系统的瞬态特性的微观分解,以从模拟结果中提取显微镜信息。第一原理分析为分析物质中的非平衡电子动力学开辟了一条新的途径,并提供了与复杂的实验技术相辅相成的基本理解。
Nonequilibrium electron dynamics in solids is an important subject from both fundamental and technological points of view. The recent development of laser technology has enabled us to study ultrafast electron dynamics in the time domain. First-principles calculation is a powerful tool for analyzing such complex electron dynamics and clarifying the physics behind the experimental observation. In this article, we review the recent development of the first-principles calculation for light-induced electron dynamics in solids by revising its application to recent attosecond experiments. The electron dynamics calculations offer an accurate description of static and transient optical properties of solids and provide physics insight into light-induced electron dynamics. Furthermore, the microscopic decomposition of transient properties of nonequilibrium systems has been developed to extract microscopic information from the simulation results. The first-principles analysis opened a novel path to analyze the nonequilibrium electron dynamics in matter and to provide the fundamental understanding complementarily with the sophisticated experimental technique.
