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…
Ab Initio Simulation of Electrical Currents Induced by Ultrafast Laser Excitation of Dielectric Materials
Georg Wachter, Christoph Lemell, Joachim Burgdörfer +3
We theoretically investigate the generation of ultrafast currents in insulators induced by strong few-cycle laser pulses. Ab initio simulations based on time-dependent density func…
