A variational polaron wave function pioneered by Toyozawa is utilized to elucidate exciton-phonon correlations in a generalized Holstein Hamiltonian in the simultaneous presence of diagonal and off-diagonal exciton-phonon couplings. We show that a simple analysis of quantum entanglement between exci...
