Title:Coherent control of ultrafast dynamics: How smart laser pulses can guide molecular processes
Date:Wed Jan 21, 2004
Start:14.30 hrs.
Location:FWN-Building 5114.0004
Host:K. Duppen


Coherent control aims to steer a quantum-mechanical system toward a desired outcome by exploiting interference effects. In a closed-loop experiment combining adaptive femtosecond pulse shaping, molecular feedback, and a learning algorithm, even systems considered intractable on an ab initio quantum-mechanical level may be explored. For example, we recently used this technique to demonstrate control over the biological function of photosynthetic light harvesting [Herek et al., Nature (2002) 417:533-535]. The applicability of this approach to biomolecules has opened new access for spectroscopic studies that will provide insight into how nature designs systems for optimal performance.

This talk will provide an overview of various pulse shaping methodologies and their application to coherent control experiments aimed at unraveling reaction mechanisms in complex systems.
