Now collecting the Hamiltonians from eqs.(4), (12) and (13), the total energy of the interacting exciton-radia-tion system is obtained in the form [Pg.109]

Charge transfer excitations simulated by quasi-particle techniques lack the electron-hole interaction (excitonic effect) because the two excess charges [Pg.68]

Above mathematics shows that the changes in the model Hamiltonian (1) that do not involve the exciton-phonon coupling terms, - for instance inclusion the exciton-exciton (electron-electron) interaction, lead only to the respective change of in Eqs.(16). [Pg.453]

Hamiltonians equivalent to (1) have been used by many authors for the consideration of a wide variety of problems which relate to the interaction of electrons or excitons with the locaJ environment in solids [22-25]. The model with a Hamiltonian containing the terms describing the interaction between excitons or electrons also allows for the use of NDCPA. For example, the Hamiltonian (1) in which the electron-electron interaction terms axe taken into account becomes equivalent to the Hamiltonians (for instance, of Holstein type) of some theories of superconductivity [26-28].
