A new nonlinear integral equation describing the thermodynamics of the Heisenberg spin chain has been derived based on the t - W relation of the quantum transfer matrices. This method is not limited to this specific model but can be generalized to other lattice quantum integrable models, providing an accurate calculation of the free energy.
A new nonlinear integral equation (NLIE) describing the thermodynamics of the Heisenberg spin chain is derived based on the t - W relation of the quantum transfer matrices. The free energy of the system in a magnetic field is thus obtained by solving the NLIE. This method can be generalized to other lattice quantum integrable models. Taking the SU(3)-invariant quantum spin chain as an example, we construct the corre- sponding NLIEs and compute the free energy. The present results coincide exactly with those obtained via other methods previously.
