Ultrafast Molecular Sciences

Ultrafast laser science has led to significant progress in molecular dynamics studies, particularly for the difficult but general case of non-Born-Oppenheimer dynamics. Quantum control methods further enhance molecular dynamics studies by permitting direct Molecular Frame measurements. As laser fields get stronger, a sub-cycle (attosecond) physics emerges, leading to new probes of driven multi-electron dynamics in polyatomic molecules. In condensed phases, ultrafast lasers permit simplified approaches to label-free nonlinear microscopy of live cells and tissues.
