The vertex interaction is given by cos(k j · φ) where k j (j = 1, 2, …, M) are momentum vectors and φ is an N-component scalar field. OSTI.GOV Journal Article: Comparison of renormalization group schemes for sine-Gordon-type models The renormalization group is a fundamental and powerful tool to investigate the property of quantum systems [1–15].The physics of a many-body system is sometimes captured by the analysis of an effective field theory model [16–19].Typically, effective field theory models are the ϕ 4 model, the non-linear sigma model and the sine-Gordon model. Each of these models represents universality as CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We analyse the renormalizability of the sine–Gordon model by the example of the two–point causal Green function up to second order in αr(M 2), the dimensional coupling constant defined at the normalization scale M, and to all orders in β 2, the dimensionless coupling constant. The sine-Gordon equation is a nonlinear hyperbolic partial differential equation in 1 + 1 dimensions involving the d'Alembert operator and the sine of the unknown function. It was originally introduced by Edmond Bour () in the course of study of surfaces of constant negative curvature as the Gauss–Codazzi equation for surfaces of curvature −1 in 3-space, and rediscovered by Frenkel and We analyse the renormalizability of the sine-Gordon model by the example of the two-point Green function up to second order in alpha_r(M), the dimensional The renormalization group flow is presented for the two-dimensional sine-Gordon model within the framework of the functional renormalization group method by sine-Gordon model: advanced topics J.

Sine gordon model renormalization

An effective theory for the slow modes is derived and rescaled to yield the flow equations for the model. We investigate the chiral sine-Gordon model using the renormalization group method. The chiral sine-Gordon model is a model for G-valued fields and describes a new class of phase transitions, where G is a compact Lie group. We show that the model is renormalizable by means of a perturbation expansion and we derive beta functions of the renormalization group theory. Abstract. The scheme dependence of the renormalization group (RG) flow has been investigated in the local potential approximation for two-dimensional periodic, sine-Gordon type field-theoretic models discussing the applicability of various functional RG methods in detail.

A perturbative renormalization group procedure is described, in which the sine-Gordon field is decomposed into slow and fast modes. An effective theory for the slow modes is derived and rescaled to yield the flow equations for the model. We analyse the renormalizability of the sine-Gordon model by the example of the two-point Green function up to second order in alpha_r(M), the dimensional coupling constant defined at the normalization scale M, and to all orders in beta^2, the dimensionless coupling constant.

We renormalize the (1+1)-dimensional sine-Gordon model by placing it on a Euclidean lattice, and study the renormalization group flow. We start with a compactified theory with controllable vortex activity. In the continuum limit the theory has a phase in which the kink current is anomalous, with divergence given by the vortex density. The phase structure is quite complicated.
