Instantaneous dynamics and quantum control fields — •Volker Engel¹, Stefanie Gräfe¹, and Christoph Meier² — ¹Institut für Physikalische Chemie, Universität Würzburg, Am Hubland, 97074 Würzburg — ²Laboratoire de Collisions, Agrégats et Reactivite, IRSAMC,Universite Paul Sabatier,31062 Toulouse, France

The relation between laser pulses serving the purpose of controlling elementary molecular processes and the instantaneous dynamics of the perturbed system is investigated. The application of the conditions assuring a controlled change of the expectation value of an observable directly links the system motion to the external perturbation. Several numerical applications document that the derived control fields are efficient and can be interpreted clearly on physical grounds.
