Global-local ansatz and dynamical coherent potential approximation study of off-diagonal exciton-phonon coupling
We study the generalized Holstein Hamiltonian in the simultaneous presence of diagonal and off-diagonal exciton-phonon couplings using the global-local Ansatz and the dynamical coherent potential approximation (under the Hartree approximation). The former yields detailed exciton-phonon correlations...
