Gauge Invariance beyond the Electric Dipole Approximation
Ryoji Anzaki, Yasushi Shinohara, Takeshi Sato +1
We study the gauge invariance of laser-matter interaction. The velocity gauge where the vector potential is expanded to the -th order with respect to the spatial coordinate, and…
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…
