Abstract

The free energy of the supersymmetric t-J model is expressed in terms of finite temperature excitations away from thermodynamic equilibrium. This reveals that the free energy has the form of noninteracting fermions with temperature dependent excitation spectra. We also discuss the ground state and zero temperature excitations.
