Comment on "Ising Spin Glasses in a Magnetic Field"
E. Marinari, G. Parisi, F. Zuliani
Abstract
In ref. cond-mat/9811419 Houdayer and Martin analyze the T=0 3d EA spin glass with a magnetic field B. By using a new, powerful method, they determine an effective critical field Bc as a function of the lattice size L. They use their results to deduce that the model is behaving like in the droplet approach and not like the mean-field theory. We show here, by using some unpublished data, that this very interesting method and numerical results are completely compatible with the behavior implied by the Replica Symmetry Breaking theory.
