Novel Position-Space Renormalization Group for Bond Directed Percolation in Two Dimensions
نویسندگان
چکیده
A new position-space renormalization group approach is investigated for bond directed percolation in two dimensions. The threshold value for the bond occupation probabilities is found to be pc = 0.6443. Correlation length exponents on time (parallel) and space (transverse) directions are found to be ν‖ = 1.719 and ν⊥ = 1.076, respectively, which are in very good agreement with the best known series expansion results. PACS numbers : 64.60.Ak, 64.60.Ht, 05.70.Jk

Directed Percolation on a 2D Triangular Lattice
We study directed percolation on a 2D triangular lattice where the forward direction is perpendicular to one of the lattice axes. In addition to the geometrical description, an equivalent dynamic description of the model is presented. Simulations are performed based on an algorithm from the dynamic description to obtain the critical probability of bond occupation as pc ≈ 0.522. A mean field the...
متن کاملA real-space renormalization group for site and bond percolation?
We develop a real-space renormalization group which renormalizes probabilities directly in the percolation problem. An exact transformation is given in one dimension, and a cluster approach is presented for other lattices. Our results are in excellent agreement with series calculations for the critical percolation concentration p, (both site and bond), and in good agreement for the correlation ...
متن کاملRenormalization group study of a kinetically constrained model for strong glasses.
We derive a dynamic field theory for a kinetically constrained model, based on the Fredrickson-Andersen model, which we expect to describe the properties of an Arrhenius (strong) supercooled liquid at the coarse-grained level. We study this field theory using the renormalization group. For mesoscopic length and time scales, and for space dimension d>/=2 , the behavior of the model is governed b...
متن کاملSelf-avoiding Walks on Random Networks of Resistors and Diodes
We study the self-avoiding walks (SAW) on a square lattice whose various degrees of randomness encompasses many different random networks, including the incipient clusters of the directed, mixed and isotropic bond percolation. We apply the position-space renormalization group (PSRG) method and demonstrate that within the framework of this method one is bound to find that the critical exponent v...
متن کاملCrossover from Isotropic to Directed Percolation
Percolation clusters are probably the simplest example for scale–invariant structures which either are governed by isotropic scaling–laws (“self–similarity”) or — as in the case of directed percolation — may display anisotropic scaling behavior (“self–affinity”). Taking advantage of the fact that both isotropic and directed bond percolation (with one preferred direction) may be mapped onto corr...
