Recent developments in attosecond experimental techniques have enabled the observation of ultrafast electron dynamics in solids with attosecond time resolution. These experiments provide valuable insights into the nonequilibrium dynamics of matter. However, developing a microscopic interpretation of the observed phenomena is challenging due to the complex electronic structures of solids.
Quantum electron dynamics simulation, based on the time-dependent density functional theory, serves as a powerful tool to elucidate these intricate electron dynamics. In this talk, I will introduce a first-principles approach to investigating attosecond phenomena in solids and its applications to magnetic systems. Additionally, I will discuss attosecond spin-dynamics spectroscopy, extended from attosecond transient absorption spectroscopy, based on the insights gained from first-principles simulations.
