Simulating the control of molecular reactions via modulated light fields: From gas phase to solution — •Regina de Vivie-Riedle — LMU München

Optimal control theory and optimal control experiments are state-of-the-art tools to control quantum systems. Both methods have been demonstrated successfully for numerous applications in molecular physics, chemistry and biology. Modulated light pulses could be realized, driving these various control processes. The accessibility of few femtosecond or even attoseconds pulses opens the door further to direct observation and steering of electron dynamics. Next to the control efficiency, a key issue is the understanding of the control mechanism. An obvious way is to seek support from theory. In this contribution theoretical studies will be presented that highlight control events ranging from chemical reactions via the steering of nuclear and electronic wavepackets [1,2,3] over directional control of bond breaking in symmetric molecules [4] to control scenarios in solution.
