摘要：
We derive the spectrum and thermodynamics of the one-dimensional 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 the free energy.
