- W1974927150 abstract "Abstract Unconventional, direct thermodynamic perturbation techniques are required, if the unperturbed Hamiltonian contains already many-body correlations, or if operators are involved, which do not obey boson- or fermion-communication relations. These techniques and their various versions (e.g. resolvent methods, regularized Goldstone diagrams, Brillouin-Wigner type expansions) are treated from a unifying point of view. Applications to magnetic impurities, local two-level systems, intermediate valence models are given. The derivation of dispersion relations is reviewed as well as the intermediate state analysis of Feynman diagrams in terms of Goldstone diagrams at finite temperatures." @default.
