Abstract

Traditional all-optical enantiosensitive techniques arise due to the interference of electric dipole transitions (E1) with magnetic dipole (M1) or electric quadrupole (E2) transitions [1]; they are thus rather inefficient due to the relative weakness of the M1 and E2 transitions with respect to the E1 ones. Recently, a new enantiosensitive method based on enantiosensitive interference of E1-only transitions was proposed in Ref. [2]. The method is based on the transitions being driven by synthetic chiral light (SCL), i.e. light that displays chirality in time and not in space. The chirality is encoded in the Lissajous curve drawn by the electric field vector over one optical cycle, rather than in its propagation in space as in E1-M1 or E1-E2 techniques [1], leading to particularly strong enantiosensitive signals [2].
