Thermodynamics of the Two-Dimensional Hubbard Model Based on the Exact Two-Body S-Matrix

A new analytic treatment of the 2D Hubbard model at finite temperature and chemical potential is presented. A next-nearest-neighbor hopping term of strength t is included. This analysis is based upon a formulation of the statistical mechanics of particles in terms of the S-matrix. We show that for U...
