Multielectron dynamics plays an important role when atoms and molecules are subject to ultrashort intense laser pulses. Numerical investigations of multielectron dynamics and correlation effects require highly nonperturbative treatments, which are very challenging. In order to tackle this challenge, the time-dependent multiconfiguration self-consistent-field (TD-MCSCF) methods have been developed. In this contribution, as a starting point of TD-MCSCF methods, we report 3-dimensional real-space implementation of the time-dependent Hartree-Fock (TDHF) method for diatomic molecules, with which stable and highly accurate simulations of strong-field phenomena are achieved within reasonable computational cost.
