Resonance Energy Transfer Involving Chiral Molecules and Macroscopic Environment — •Janine C. Franz1,2, Stefan Yoshi Buhmann1, and A. Salam3 — 1University Kassel, Germany — 2University Freiburg, Germany — 3Wake Forest University, Winston-Salem, USA
Resonance energy transfer between chiral molecules can be used to discriminate between different enantiomers. The transfer rate between chiral molecules consists of nondiscriminatory and discriminatory parts. We show that their ratio is usually larger in the far zone regime and that the degree of discrimination can be modified when considering a surrounding medium. We highlight the importance of local field effects on the degree of discrimination, predict the optimum dielectric medium for general identical chiral molecules for discrimination, and show that exotic media can even invert the discriminatory effect. When considering a chiral medium, the environment can actively participate in the discrimination, but the local-field corrections become more involved. We show that the local-field corrections in a chiral medium then lead to a surprising effect in the discrimination.
