Efficient simulation of multielectron dynamics in molecules under intense laser pulses: Implementation of the multiconfiguration time-dependent Hartree-Fock method based on the adaptive finite element method

Yuki Orimo, Takeshi Sato, Kenichi L. Ishikawa

We present an implementation of the multiconfiguration time-dependent Hartree-Fock method based on the adaptive finite element method for molecules under intense laser pulses. For…

Atomic real-space perspective of light-field-driven currents in graphene

Yuya Morimoto, Yasushi Shinohara, Kenichi L. Ishikawa +1

When graphene is exposed to a strong few-cycle optical field, a directional electric current can be induced depending on the carrier-envelope phase of the field. This phenomenon ha…

Exact solutions, spectrum properties, and hierarchical structures of the multiple temperature model

Hiroki Katow, Kenichi L. Ishikawa

Recent developments of ultrafast laser pulse techniques enable us to study the subpicosecond scale dynamics out of thermal equilibrium. Multiple temperature models are frequently u…
