Enantioselctive Occupation Transfer via Berry Phase Cycling — •Aycke Roos1, Pablo Maier1, and Olga Smirnova1,2 — 1Max-Born-Institut — 2Technische Universität Berlin
A chiral molecule interacting with synthetic chiral light acquires geometric properties as the Lissajous figure of this light is adiabatically deformed in a cycle. During this cycle the electronic wave function of the molecule acquires a geometric (Berry) phase.
The phase serves as the fundamental quantity that encapsulates the geometric interplay between field and molecule. It naturally provides a clear geometric picture stripped from any dynamical processes. It further enables the identification of explicit polarization protocols to maximize the enantioselective excitation of one of one enantiomers. In particular, we find that a reversal of the temporal polarization vector trajectory quantified by the winding number leads to a switch between preferential excitation of left-or right handed molecules.
