Ultrafast chirality: twisting light to twist electrons”
Chair: Fernando Martin (Universitdad Autónoma de Madrid, ES)

Abstract: I will describe several new, extremely efficient approaches to chiral discrimination and enantio-sensitive molecular manipulation, which take advantage of ultrafast electronic response [1,2].  One of them is based on the   new concept of synthetic chiral light [3,4], which can be used to trigger bright nonlinear optical response in the molecule of a desired handedness while keeping its mirror twin dark in the same frequency range. The other is based on the new concept of  geometric magnetism in photoionization of chiral molecules and leads to a new class of enantiosensitive observables in photoionization [5].
