In the presented work, the static coherent states method (SCS) is introduced to investigate quantum electron dynamics in a one or two-electron laser-induced system. The SCS method solves the time-dependent Schrödinger equation (TDSE) both in imaginary and real times on the base of a static grid of coherent states. Moreover, classical dynamics is considered for the nuclei by solving their Newtonian equation of motion. Implementing classical nuclear dynamics, the electronic state potential energy curves of H2+ in the absence and presence of an ultra-short intense laser field is computed. We use this method to investigate charge migration in H2+. In particular, we find that the charge migration time increases exponentially with internuclear distance. We also observe substantial charge localization for sufficiently long molecular bonds.
