Two-hole problem in the t-J model: A canonical transformation approach
V. I. Belinicher, A. L. Chernyshev, V. A. Shubin
The t-J model in the spinless-fermion representation is studied. An effective Hamiltonian for the quasiparticles is derived using canonical transformation approach. It is shown tha…

Single hole dispersion relation for the real CuO plane
V. I. Belinicher, A. L. Chernyshev, V. A. Shubin
Dispersion relation for the CuO hole is calculated basing on the {\it generalized} -- model, recently derived from the three-band one. Numerical ranges for al…

Generalized -- 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 -- model is presented. Two types of the additional -terms are discussed. The set of ranges of the a…
