Abstract: The composite nature of the exciton gives rise to very many carrier exchanges which cannot be accounted correctly through an effective Hamiltonian for bosonized particles. This forced us to construct a new manybody procedure [For a short review, see M. Combescot, O. Betbeder-Matibet, Solid State Commun. 134 (2005) 11]. Here we report a few important aspects of this procedure, using Shiva diagrams [M. Combescot, O. Betbeder-Matibet, Eur. Phys. J. B 55 (2007) 63] which greatly help not only to visualize, but al…
