Abstract
Using a collective-mode Monte Carlo method (the Wolff-Swendsen-Wang al gorithm), we compute the spin stiffness of the two-dimensional classic al Heisenberg model. We show that it is the relevant physical quantity to investigate the behaviour of the model in the very low-temperature range inaccessible to previous studies based on correlation length an d susceptibility calculations.
