An Extension of the Thermal Bethe Ansatz

— One-Dimensional Hubbard Model —

(Received February 5, 1990)

Abstract:

The thermodynamics of the one-dimensional Hubbard model is reduced to a system of algebraic equations through an extension of our thermal Bethe ansatz. This new formalism is free from the string conjecture, or more basically from the unproven assumption of the completeness of the Bethe states.
