Spectrum and Thermodynamics of the 1 D Supersymmetric t - J Model with 1 / r 2 Exchange and Hopping

Abstract

We derive the spectrum and thermodynamics of the 1D supersymmetric t-J model with long range hopping and spin exchange using a set of maximal spin eigenstates. This spectrum confirms the recent conjecture that the asymptotic Bethe-ansatz spectrum is exact. By empirically determining the spinon degeneracies of each state, we are able to explicitly construct… (More)
