Replica Symmetry Breaking in Renormalization: Application to the Randomly Pinned Planar Flux Array
نویسنده
چکیده
Trie randomly pinned planar flux bne array is supposed to show a phase transition to a vortex glass phase at low temperatures. This transition bas been examined by using a mapping onto a 2D XY-mortel with random anisotropy but without vortices and applying a

Replica Symmetry Breaking Instability in the 2D XY Model in a Random Field.
We study the 2D vortex-free XY model in a random field, a model for randomly pinned flux lines in a plane. We construct controlled RG recursion relations which allow for replica symmetry breaking (RSB). The fixed point previously found by Cardy and Ostlund in the glass phase T < Tc is unstable to RSB. The susceptibility χ associated to infinitesimal RSB perturbation in the high-temperature phas...
متن کاملA Computational Study to Find the Vibrational Modes Connected with Specific Molecular Structures of Calculated Compound
The purpose of this research is to provide a deeper understanding of the planar high- symmetry configuration instability. In the ideal case, the distortion corresponds to the movements of nuclei along normal modes that belong to non-totally symmetric irreps of the high symmertry (HS) point group of molecule. The analysis of the structural distortion from the HS nuclear arrangements of the JT ac...
متن کاملDerivation of the Functional Renormalization Group β-function at order 1/N for manifolds pinned by disorder
In an earlier publication, we have introduced a method to obtain, at large N , the effective action for d-dimensional manifolds in a N -dimensional disordered environment. This allowed to obtain the Functional Renormalization Group (FRG) equation for N = ∞ and was shown to reproduce, with no need for ultrametric replica symmetry breaking, the predictions of the Mézard-Parisi solution. Here we c...
متن کاملDisordered Systems and the Functional Renormalization Group, a Pedagogical Introduction
In this article, we review basic facts about disordered systems, especially the existence of many metastable states and and the resulting failure of dimensional reduction. Besides techniques based on the Gaussian variational method and replica-symmetry breaking (RSB), the functional renormalization group (FRG) is the only general method capable of attacking strongly disordered systems. We expla...
متن کاملA ug 2 00 3 Critical behavior of disordered systems with replica symmetry breaking
A field-theoretic description of the critical behavior of weakly disordered systems with a p-component order parameter is given. For systems of an arbitrary dimension in the range from three to four, a renormalization group analysis of the effective replica Hamiltonian of the model with an interaction potential without replica symmetry is given in the two-loop approximation. For the case of the...
