Title: Coherent Control of Photoassociation at High and Low Temperature

Speaker: Christiane Koch, Institut für Physik, Universität Kassel


Molecules can be assembled from atoms using laser light. This process is termed photoassociation. With the advent of femtosecond lasers and pulse shaping techniques, photoassociation became a natural candidate for coherent control of a binary reaction. While coherent control has been very successful for unimolecular processes, controlling a binary reaction has remained an open challenge. The main difference between unimolecular processes and a binary reaction lies in the initial state - a single or few well-defined bound quantum states vs an incoherent continuum of scattering states. For a binary reaction, the nature of the scattering continuum is mainly determined by the temperature, and thus quantum purity, of the initial ensemble. I will discuss the possibilities to control photoassociation at high and ultralow temperatures.

Coffee, tee and cake will be served at 15:05.
