kadanoff real space variational renormalization group
10/14/2014 ∙ by Pankaj Mehta, et al. Kadanoff’s variational RG scheme introduces coarse … Downloadable (with restrictions)! The lower-bound variational approximation to the renormalization group transformation (LBV ARG) developed by Kadanoff is applied to the triangular Ising lattice. In the early 1970's Wilson showed how Kadanoff's rescaling could be explicitly carried out near the fixed point of a flow in Hamiltonian space. ∙ 0 ∙ share . The Migdal-Kadanoff real-space renormalization schemes are studied on the dual lattice for spin and gauge theories with Z(N) symmetry. In this paper we apply the Migdal-Kadanoff … proximate method is a class of variational “real-space” renormalization schemes introduced by Kadanoff for per-forming RG on spin systems [14, 16, 17]. The position-space methods used so far for the semi- infinite Ising model include cell cluster expansions [8, 9, 11], cumulant expansions [9, 12], and Kadanoffs variational method [10]. For certain values of the variational parameter p the renormalization group … A variational extension of the Migdal-Kadanoff real space renormalization group method is applied to a recently proposed d-dimensional lattice model describing some aspects of molecular orientation in … Deep learning is a broad set of techniques that uses … He made the first practical renormalization-group calculation of … The approximation is applied to cells of … An exact mapping between the Variational Renormalization Group and Deep Learning. The XY model in d dimensions is studied by means of a variational real space renormalization group transformation. Real Space Migdal–Kadanoff Renormalisation of Glassy Systems: Recent Results and a Critical Assessment ... that the spin-glass transition in a field and the glass transition are governed by zero-temperature fixed points of the renormalization group … His contributions had an enormous impact. Leo Kadanoff has worked in many fields of statistical mechanics. Contrary to an earlier computation in the same framework for the d = 2 case, we find that a low order operator basis truncation is highly unstable. Abstract. This holds in particular for critical phenomena, where he explained Widom’s homogeneity laws by means of block-spin transformations and laid the basis for Wilson’s renormalization group …
