Coherent and incoherent contributions to the carrier-envelope phase control of wave packet localization in quantum double wells — •Kilian Hader — Institut für Physikalische und Theoretische Chemie, Emil-Fischer-Str. 42, Universität Würzburg, 97074 Würzburg, Germany

We study laser excitation processes in a double well potential. The possibility to influence localization via the carrier-envelope phase (CEP) of a laser pulse is investigated for various situations which differ in the nature of the initial state prior to the laser interactions. In more detail, the CEP-dependence of asymmetries in the case where initially the system is described by localized wave packets, eigenstates or incoherent mixtures are calculated and interpreted within time-dependent perturbation theory. It is investigated which contributions to the asymmetry exist and how they can be modified to reveal a more or less pronounced CEP-effect.
