Exact ground state correlations in the supersymmetric 1 r2 exchange t-J model

Abstract

Some ground state static correlation functions for the 1 r2 exchange t-J model of Kuramoto and Yokoyama are calculated exactly. The correlations calculated are the pair distribution functions between two down spins, a down spin and a hole, and two holes, and the one-body density matrix (equal time retarded Green's function) for holes. © 1995.
