Description

We introduce the concept of temporal geometry, which encompasses geometric and topological properties of temporal shapes, e.g. trajectories traced by a tip of a time-dependent vector, and apply it to ultrafast electron currents in chiral molecules. The curvature and connection emerge as ubiquitous features of photoexcited chiral electron dynamics opening a way to ultrafast, topologically non-trivial, enantio-sensitive chemical dynamics and new highly-sensitive robust chiral observables.

Coffee, tea and cake will be served at 1:45 pm.
