Exact Results of the 1D 1/r2 Supersymmetric t-J Model without Translational Invariance
Abstract
In this work, we continue the study of the supersymmetric t-J model with 1/r2 hopping and exchange without translational invariance. A set of Jastrow wavefunctions are obtained for the system, with eigenenergies explicitly calculated. The ground state of the t-J model is included in this set of wavefunctions. The spectrum of this t-J model consists of equal-distant energy levels which are highly degenerate.
