“…A good review on the subject can be found in [2]. The most important examples for the less-known models are also the BTW sandpile model [10][11][12], the watersheds [13], the graphene system [14,15], the normal state of the YBCO superconducting planes [16], the random field Ising model [17], the Ising model on the * morteza.nattagh@gmail.com percolation systems [18], the (2 + 1)-dimensional growing surfaces [19], the Darcy model of fluid propagation in the porous media [20] and the three-state Potts model [21]. Many aspects of this model are known, ranging from its Fokker-Planck equation [22], to its relation to the other models like the Coulomb gases [2], and also many statistical features (SLE predictions) of the the random curves are kown, such as the left passage probability [4], the fractal dimension, and the Cardy's crossing probability [2].…”
