Griffiths singularities in the two-dimensional diluted Ising model
Juan Jesus Ruiz-Lorenzo
We study numerically the probability distribution of the Yang - Lee zeroes inside the Griffiths phase for the two-dimensional site diluted Ising model and we check that the shape of this distribution is that predicted in previous analytical works. By studying the finite-size scaling of the averaged smallest zero at the phase transition we extract, for two values of the dilution, the anomalous dimension, , which agrees very well with the previous estimated values.
