Strong-coupling expansion of lattice O(N) sigma models

High Energy Physics - Lattice 2009-10-28 v1

Abstract

We report progress in the computation and analysis of strong-coupling series of two- and three-dimensional O(N){\rm O}(N) σ\sigma models. We show that, through a combination of long strong-coupling series and judicious choice of observables, one can compute continuum quantities reliably and with a precision at least comparable with the best available Monte Carlo data.
