RT Journal Article T1 Ising exponents in the two-dimensional site-diluted Ising model A1 Ballesteros, H. G. A1 Fernández Pérez, Luis Antonio A1 Martín Mayor, Víctor A1 Muñoz Sudupe, Antonio A1 Parisi, G. A1 Ruiz Lorenzo, J. J. AB We study the site-diluted Ising model in two dimensions with Monte Carlo simulations. Using finite-size scaling techniques we compute the critical exponents observing deviations from the pure Ising ones. The differences can be explained as the effects of logarithmic corrections, without requiring to change the Universality Class.
