The universality of the crossing probability pi(hs) of a system to percolate only in the horizontal direction was investigated numerically by a cluster Monte Carlo algorithm for the q-state Pottsâ€¦ (More)

Using Monte Carlo techniques, the twoâ€“dimensional siteâ€“diluted Ising model is studied. In particular, properties of the specific heat, its critical behaviour and the emergence of a nonâ€“singularâ€¦ (More)
