Spin-orbit interactions between interchain excitations in conjugated polymers

Abstract:

Motivated by the reported enhanced singlet exciton yield in light-emitting polymers, we investigate spin-orbit coupling between Coulombically bound interchain excitations. We show theoretically that because of the close similarity of the singlet and triplet interchain wave functions, spin-orbit coupling between these states is negligible. Using density matrix renormalization group calculations on model systems, we confirm these theoretical predictions: spin-orbit coupling between interchain s...
