RT Journal Article T1 Universal critical behavior of the two-dimensional Ising spin glass A1 Fernández Pérez, Luis Antonio A1 Marinari, E. A1 Martín Mayor, Víctor A1 Parisi, G. A1 Ruiz Lorenzo, J. J. AB We use finite size scaling to study Ising spin glasses in two spatial dimensions. The issue of universality is addressed by comparing discrete and continuous probability distributions for the quenched random couplings. The sophisticated temperature dependency of the scaling fields is identified as the major obstacle that has impeded a complete analysis. Once temperature is relinquished in favor of the correlation length as the basic variable, we obtain a reliable estimation of the anomalous dimension and of the thermal critical exponent. Universality among binary and Gaussian couplings is confirmed to a high numerical accuracy.
