Medium-assisted chiral discrimination via resonance energy transfer — •Janine Christine Franz1, Stefan Yoshi Buhmann2, and Akbar Salam3 — 1University of Freiburg, Germany — 2University of Kassel, Germany — 3Wake Forest University, Winston-Salem, USA
Resonance energy transfer between two chiral molecules can be used in principle to discriminate enantiomers [1]. Using macroscopic quantum electrodynamics, we study how to enhance and control this effect by means of an intervening medium and propose a distinct, but related way to discriminate between enantiomers by using a medium with known chirality [2].
When embedding molecules in a macroscopic medium, the microscopic structure of the medium close to the embedded molecule needs to be taken into account; we achieve this by using the so-called local-field correction. We present the influence of a magneto-(di)electric medium surrounding the energy-exchanging molecules, where exotic media have a non-trivial impact on the degree of discrimination [3]. When considering a chiral medium that takes an active part in the chiral discrimination, we find that considering local-field effects results in a surprising prediction for the discrimination.
