VARIATIONAL LOCALIZED-SITE CLUSTER EXPANSIONS .11. COHERENT STATE DERIVATION OF EFFECTIVE HEISENBERG HAMILTONIANS uri icon

abstract

  • A variational derivation of Heisenberg or valencebond models from a Hubbard (or PariserParrPople) Hamiltonian is described. Calculations within a loworder approximation are carried out for linearchain and graphite lattices. The results seem to be quite accurate with little computational effort when compared with other approaches. Copyright 1983 John Wiley & Sons, Inc.
