Effects of a k-dependent Hybridization on the Fermi Surface of an Extended $d-p$ Hubbard Model

D. M. Lalis, E. J. Calegari, L. C. Prauchner +1

The topology of the Fermi surface of an extended $d-p$ Hubbard model is investigated using the Green's function technique in a n-pole approximation. The effects of the $d-p$ hybrid…
