Characteristics of wavepacket evolution from quantum control landscapes — •Philipp Marquetand1, Patrick Nürnberger2, Gerhard Vogt2, Tobias Brixner2, and Volker Engel11Institut für Physikalische Chemie, Universität Würzburg, Am Hubland, 97074 Würzburg — 2Physikalisches Institut , Universität Würzburg, Am Hubland, 97074 Würzburg

We are using shaped dump pulses to map the evolution of a wavepacket in an excited state. By systematic variation of selected pulse parameters, we monitor the efficiency for a transition to the groundstate. From the resulting two-dimensional fitness landscapes information on the wavepacket shape and the system under study can be deduced. Results from simplified model calculations are presented and first experiments on the retinal photoisomerization reaction in bacteriorhodopsin have been performed.
