NONLOCAL THIRRING MODEL AT FINITE-TEMPERATURE

We extend a recently proposed non-local and non-covariant version of t he Thirring model to the finite-temperature case. We obtain a complete ly bosonized expression for the partition function, describing the the rmodynamics of the collective modes which are the underlying excitatio ns of this system. From this result we derive closed formulae for the free-energy, specific-heat, two-point correlation functions and moment um distribution, as functionals of electron-electron coupling potentia ls.
