Exact calculations are presented for the ground state of linear antiferromagnetic Heisenberg chains with open ends. The wave function and the energy are given for chains with N = 4, 6, and 8, and quantum number S = 1/2. It is shown that in the limit for N + 03 the ground state is probably nondegenerate and the long-range order tends to zero. The short-range… (More)
