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…
Trajectory analysis of high-harmonic generation from periodic crystals
Takuya Ikemachi, Yasushi Shinohara, Takeshi Sato +3
We theoretically study high-harmonic generation (HHG) from solids driven by intense laser pulses using a one-dimensional model periodic crystal. By numerically solving the time-dep…
Reduced-Shifted Conjugate-Gradient Method for a Green's Function: Efficient Numerical Approach in a Nano-structured Superconductor
Yuki Nagai, Yasushi Shinohara, Yasunori Futamura +1
We propose the reduced-shifted Conjugate-Gradient (RSCG) method, which is numerically efficient to calculate a matrix element of a Green's function defined as a resolvent of a Hami…
