Accurate high-harmonic spectra from time-dependent two-particle reduced density matrix theory
Fabian Lackner, Iva Březinová, Takeshi Sato +2
The accurate description of the non-linear response of many-electron systems to strong-laser fields remains a major challenge. Methods that bypass the unfavorable exponential scali…
High-harmonic generation enhanced by dynamical electron correlation
Iliya Tikhomirov, Takeshi Sato, Kenichi L. Ishikawa
We theoretically study multielectron effects in high-harmonic generation (HHG), using all-electron first-principles simulations for a one-dimensional (1D) model atom. In addition t…
Time-dependent complete-active-space self-consistent-field method for atoms: Application to high-harmonic generation
Takeshi Sato, Kenichi L. Ishikawa, Iva Brezinova +3
We present the numerical implementation of the time-dependent complete-active-space self-consistent-field (TD-CASSCF) method [Phys. Rev. A, 88, 023402 (2013)] for atoms driven by a…
