RT Journal Article T1 The four-dimensional site-diluted Ising model: A finite-size scaling study 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 Using finite-size scaling techniques, we study the critical properties of the site-diluted Ising model in four dimensions. We carry out a high-statistics Monte Carlo simulation for several values of the dilution. The results support the perturbative scenario: there is only the Ising fixed point with large logarithmic scaling corrections. We obtain, using the Perturbative Renormalization Group, functional forms for the scaling of several observables that are in agreement with the numerical data.
