Driving chiral matter by chiral light — •Alexandra Schrader, Benjamin Schwager, Christian Bohley, and Jamal Berakdar — Martin-Luther-Universität Halle-Wittenberg

Many chiral materials display a magneto-electric response which, in lowest order, can be expressed by a complex cross-coupling of the electric (magnetic) dipole moments to the magnetic (electric) fields. A number of physical properties depend on the material's chirality state and hence it is important to find ways to drive and separate objects according to their chirality. E.g., chiral molecules, which are crucial in drug manufacturing, can be chirality-specific separated by optical forces which act differently on different types of enantiomer. This theory contribution discusses how engineering the chiral characteristics of light through structuring both the spatial polarization and orbital phase allow to optimize the chiral forces and torques to steer chiral matter.

Keywords: chirality; structured light; magnetoelectric effect; enantiomer separation
