Exact solution of generalized Schulz-Shastry type models
A. Osterloh, L. Amico, U. Eckern
Abstract
A class of integrable one-dimensional models presented by Shastry and Schulz is consequently extended to the whole class of one-dimensional Hubbard- or XXZ-type models with correlated gauge-like hopping. A complete characterization concerning solvability by coordinate Bethe ansatz of this class of models is found.
