First-principles modelling for time-resolved ARPES under different pump-probe conditions
Umberto De Giovannini, Shunsuke A. Sato, Hannes Hübener +1
First-principles methods for time-resolved angular resolved photoelectron spectroscopy play a pivotal role in providing interpretation and microscopic understanding of the complex…
Two-step Brillouin zone sampling for efficient computation of electron dynamics in solids
Shunsuke A. Sato
We develop a numerical Brillouin-zone integration scheme for real-time propagation of electronic systems with time-dependent density functional theory. This scheme is based on the…
Theory for the electron excitation in dielectrics under an intense circularly polarized laser field
T. Otobe, Y. Shinohara, S. A. Sato +1
We report a Keldysh-like model for the electron transition rate in dielectrics under an intense circularly polarized laser. We assume a parabolic two-band system and the Houston fu…
Dielectric response of laser-excited silicon at finite electron temperature
S. A. Sato, Y. Shinohara, T. Otobe +1
We calculate the dielectric response of excited crystalline silicon in electron thermal equilibrium by adiabatic time-dependent density functional theory (TDDFT) to model the respo…
Efficient basis expansion for describing linear and nonlinear electron dynamics in crystalline solids
Shunsuke A. Sato, Kazuhiro Yabana
We propose an efficient basis expansion for electron orbitals to describe real-time electron dynamics in crystalline solids. Although a conventional grid representation in the thre…
