Classical optics approximations are exact for N to infinity all-to-all coupled permutationally symmetric molecular aggregates, with 1/N corrections from Raman-like single-monomer transitions.
Emitter-emitter interactions allow individual nonlinear susceptibilities to appear as vibrational sidebands in the linear spectra of quantum emitter arrays and heterodimers.
