A QUANTUM-ELECTRODYNAMIC THEORY OF INDUCED CIRCULARLY POLARIZED LUMINESCENCE

A theory of molecule-induced circulary polarised emission for a lumine scent chiral-achiral pair employing the multipolar Hamiltonian in both the Schrodinger and Heisenberg formulations of Coulomb gauge quantum electrodynamics is presented. Chirality is induced in an achiral speci es via intermolecular coupling with a chiral molecule. In the Schrodin ger picture time-dependent perturbation theory is used with intermolec ular interaction involving virtual photon exchange. In the Heisenberg framework the electric dipole moment of the achiral molecule couples t o the time-dependent Maxwell fields of the chiral source. The equivale nce of the matrix element obtained for the process using both approach es is demonstrated. The transition rate is then derived for the differ ential spontaneous emission of left- and right-circularly polarised ra diation. Various orientational averages are computed and the dependenc e of the rate expression on intermolecular separation is investigated.
