Query: Numerical signs for a transition in the 2d Random Field Ising Model at
  T=0   Intensive numerical studies of exact ground states of the 2-d ferromagnetic
random field Ising model at T=0 with gaussian distribution of fields are
presented. Standard finite size scaling analysis of the data suggests the
existence of a transition at sigma_c= 0.64 +/- 0.08. Results are compared with
existing theories and with the study of metastable avalanches in the same
model.
