Carrier Envelope Phase Effects induced by weak multicycle pulses: localized quantum dynamics in double well potentials — •Kilian Hader1,2, Klaus Renziehausen1,2, and Volker Engel1,2 — 1Institut für Physikalische und Theoretische Chemie, Uni Würzburg — 2Campus Nord, Am Hubland, Emil-Fischer-Str. 42, 97074 Würzburg, Germany
We study the laser-driven quantum dynamics in a double well potential. Within a two-pulse excitation scheme the first pulse prepares a linear combination of excited states with ungerade symmetry. The interaction with a second uncorrelated pulse of low intensity results in coherent superpositions of states with gerade and ungerade symmetry. This is associated with a localization of excited state wave packets. It is shown that the carrier envelope phase of the second laser pulse critically influences this time-dependent localization.
