Thermodynamics and Excitations of the Supersymmetric $t-J$ Model
Abstract
Description
The free energy of the supersymmetric $t-J$ model is expressed in terms of finite temperature excitations above thermodynamic equilibrium. This reveals that the free energy has the form of noninteracting fermions with temperature dependant excitation spectra. We also discuss the ground state and zero temperature excitations.
