Geometric magnetism and new enantio-sensitive observables in photoionization of chiral molecules

Abstract: Chiral molecules are instrumental for molecular recognition in living organisms. Distinguishing between two opposite enantiomers, the mirror twins of the same chiral molecule, is both vital and challenging. Geometric magnetism enables a broad class of phenomena in solids including the anomalous electron velocity, the Hall effect, and related topological observables. Here we show that ultrafast electron currents excited in chiral molecules can generate geometric fields which enable a new class of extremely effi… Show more

“…4c, from which we extract the time delay Δt = 1. The electron dynamics uncovered in this work underlies yet another consequence on the molecular response of photoexcited chiral systems: the coherent superposition of excited states induced by the pump allows to selectively filter-within a few femtoseconds-specific molecular orientations through enantiosensitive photoionization 10 . An electron moving within the coherent state superposition creates an electronic current 35…”
