摘要
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, eta, which agrees very weil with the previous estimated values.
