21 Jun 2006 | | Subject: | Strongly Correlated Electrons | | Abstract: | A microscopic theory for electronic spectrum of the CuO2 plane within an effective p-d Hubbard model is proposed. Dyson equation for the one-electron Green function in terms of the Hubbard operators is derived which is solved self-consistently for the self-energy evaluated in the noncrossing approximation. Electron scattering on spin fluctuations induced by kinematical interaction is described by a model dynamical spin susceptibility. Doping and temperature dependence of electron dispersions, spectral functions, the Fermi surface and the coupling constant are studied. | | Source: | arXiv, cond-mat/0606557 | | Services: | Forum | Review | PDF | Favorites | |
