摘要：

Using a collective-mode Monte Carlo method (the Wolff-Swendsen-Wang algorithm), we compute the spin stiffness of the two-dimensional classical 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 and susceptibility calculations.
