Exploring wavepacket dynamics under strong laser fields — •Leticia Gonzalez — Institut f. Physikalische Chemie, Friedrich Schiller Universitaet Jena, Jena, Germany
Control of nuclear and electron dynamics in molecules is a hot topic in physical chemistry. In this contribution we investigate the effect of strong laser fields in two molecular systems. In the first case, a molecular switch is controlled by inducing dynamic Stark fields. Such strong laser fields alter the topology of the potential energy surface, creating a favorable situation to switch the nuclear dynamics from one minimum to the other. In the second example, the photo-dissociation dynamics and dissociative photo-ionization of dihalomethanes is presented. Pump-probe experiments demonstrate the creation and control of orbital hole electronic and vibrational wave packets created via strong field ionization [1]. Our simulations provide an interpretation for the experimental signals.
