Generalized $t$-$t^{\prime }$-$J$ model: parameters and single-particle spectrum for electrons and holes in copper oxides

V. I. Belinicher, A. L. Chernyshev, V. A. Shubin

A microscopically based Hamiltonian of the generalized $t$-$t^{\prime }$-$J$ model is presented. Two types of the additional $t^{\prime }$-terms are discussed. The set of ranges of the a…
