New extended high temperature series for the N-vector spin models on three-dimensional bipartite lattices

arXiv:hep-lat/9505027 · doi:10.1103/PhysRevB.52.6185

Abstract

High temperature expansions for the susceptibility and the second correlation moment of the classical N-vector model (O(N) symmetric Heisenberg model) on the sc and the bcc lattices are extended to order for arbitrary N. For N= 2,3,4.. we present revised estimates of the critical parameters from the newly computed coefficients.
