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…
Sub-Cycle Optical Response Caused by Dressed State with Phase-Locked Wavefunctions
K. Uchida, T. Otobe, T. Mochizuki +7
The coherent interaction of light with matter imprints the phase information of the light field on the wavefunction of the photon-dressed electronic state. Driving electric field,…
Time-resolved dynamical Franz-Keldysh effect under elliptically polarized laser
T. Otobe
The analytical formula for the time-resolved dynamical Franz-Keldysh effect (Tr-DFKE) under an elliptically polarized laser in sub-femtosecond time-scale is reported. The Houston f…
High-harmonic generation in alpha-quartz by the electron-hole recombination
T. Otobe
A calculation of the high-harmonic generation (HHG) in -quartz using the time-dependent density functional theory is reported. The inter-band process is attributed to the domina…
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…
