Abstract

One-dimensional models with 1/r 2 exchange have long been studied [1, 2] and have attracted renewed interest since the introduction of the spin-1/2 1/r 2-Heisenberg or Haldane-Shastry chain [3, 4] for which the ground state wave function [3, 4], the ground state correlation function [5, 2, 6] and the free energy [7, 8] are known exactly. The algebraic structure of these long-range models can be studied in detail [8, 9, 10] and even their dynamical structure factors have recently been found [11, 12, 13].
