New exactly solvable model of strongly correlated electrons motivated by high-Tc superconductivity.
We present a new model describing strongly correlated electrons on a general d-dimensional lattice. It is an extended Hubbard model and it contains the t-J model as a special case. The model naturally describes local electron pairs, which can move coherently at arbitrary momentum. By using an -pairi...
