Abstract
Controlling spatial-temporal overlap between nuclear wave packets propagating on the coupled electronic states with opposite parity by intense laser field leads to a n periodic modulation in the symmetry breaking of the coupled forward-backward electron and proton motions. The most probable directionality of electron and proton moving simultaneously in opposite directions with total electron-proton asymmetry parameter Atot e-p = 0.62 occurs at fixed carrier-envelope phases of theta = 15 degrees and 195 degrees. Analysis of the time evolution of the nuclear and the electronic-nuclear wave packets on the field-dressed potentials gives rise to newly insightful images of the nonlinear nonperturbative processes for the asymmetrical localization.
