FIG. 1.

(a) Adiabatic potential energy curves for the (solid) and (dashed) electronic states along the torsion coordinate , in eV. Planar and twisted 1,1-DFE are included. (b) Nonadiabatic coupling term between the and states (solid) and the mixing angle (dashed), in a.u. (c) -polarized adiabatic permanent dipole moments and (solid), and the transition dipole moment (dashed) between the states and , all in a.u.

FIG. 2.

Schematic representation of the control strategies and time-averaged population densities in the potentials (solid) and (dashed) for laser-free conditions, gain strategy, and loss strategy. (a) The wave packet in (solid) is excited to (dashed) with a -pulse (field-free conditions). (b) (solid) and (dashed) in control field-free conditions. (c) Gain-strategy mechanism by acceleration of the wave packet. The promoted wave packet in (dashed) goes to (solid) via the CI and the control laser excites it back to (dashed) with extra velocity. (d) (solid) and (dashed) in the gain strategy. (e) Loss-strategy mechanism by trapping the wave packet in (dashed) at the FC window. (f) (solid) and (dashed) in the loss strategy.

FIG. 3.

Evolution of the total kinetic energy of the wave packet in the three different scenarios: field-free conditions (solid), gain strategy (dash), and loss strategy (dot-dash).
