Implementation of gauge-invariant time-dependent configuration interaction singles method for three-dimensional atoms
Takuma Teramura, Takeshi Sato, Kenichi L. Ishikawa
We present a numerical implementation of the gauge-invariant time-dependent configuration interaction singles (TDCIS) method [Appl. Sci. 8, 433 (2018)] for three-dimensional atoms.…

Time-Dependent Complete-Active-Space Self-Consistent-Field Method for Ultrafast Intense Laser Science
Takeshi Sato, Yuki Orimo, Takuma Teramura +2
We present the time-dependent complete-active-space self-consistent-field (TD-CASSCF) method to simulate multielectron dynamics in ultrafast intense laser fields from the first pri…

Gauge-invariant formulation of time-dependent configuration interaction singles method
Takeshi Sato, Takuma Teramura, Kenichi L. Ishikawa
We propose a gauge-invariant formulation of the channel orbital-based time-dependent configuration interaction singles (TDCIS) method [Phys. Rev. A 74, 043420 (2006)], one of the p…
