New strategies for controlled chirality from the rovibrational dynamics of molecules — •Andrey Yachmenev — Center for Free-Electron Laser Science, Deutsches Elektronen-Synchrotron DESY, Notkestraße 85, 22607, Hamburg, Germany

Chirality is a subject of recurrent interest across many fields of science, from the parity violation effects in fundamental physics to the enantiomeric recognition in biochemical reactions and ultimately the evolution of terrestrial life and the origins of homochirality. The development of experimental methods to study chiral molecular phenomena is therefore very important. In recent years, a number of groundbreaking techniques have been proposed and realised providing far more sensitive probes of molecular chirality than traditional chiroptical methods [1-4], and that at the ultrafast time-scales.

In my talk, I will present alternative approaches to ultrafast probes of molecular chirality, that are based on the strong-field controlled ro-vibrational dynamics of molecules. In particular, I will focus on the methods for inducing dynamic chirality in statically achiral molecules [5], efficient spatial separation of chiral molecules [6], as well as detecting the enantiomeric excess.
