Strong-coupling Expansion of Lattice O(n) Models 1. Computation of Strong-coupling Series


We report progress in the computation and analysis of strong-coupling series of two-and three-dimensional O(N) 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. We… (More)
