With a general Gaussian wave functional, the authors investigate the mass renormalization in the sine-Gordon model. At the phase transition point, the sine-Gordon system tends to a system of massless free bosons which possesses conformal symmetry.

We investigate the renormalization group theory of generalized multi-vertex sine- Gordon model by employing the dimensional regularization method and also 23 Feb 2021 the quantum sine-Gordon (qSG) model in 1+1 space-time dimensions. We analyze the lattice model using the density matrix renormalization sine-Gordon model which preserves the locality of certain operators. The reduced model We use the renormalized coupling constant ~ = ~-y/(8~. — y). Editor: J.-P. Blaizot. Abstract.

We derive renormalization group equations for the generalized sine-Gordon model by regularizing the divergence based on the dimensional method.

A perturbative renormalization group procedure is 2005-05-01 2013-06-01 The functional renormalization group treatment is presented for the two-dimensional sine-Gordon model including a bilocal term in the potential, which contributes to the flow at the tree level. It is shown that the flow of the bilocal term can substitute the evolution of the wave function renormalization constant, since it can recover the Kosterlitz–Thouless type phase transition. 1980-10-01 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.

We shall use a functional renormalization-group RG scheme to study the model at ﬁnite temperatures. Our ap-proach is as follows: we perform a simple transformation which maps the PT model to a sine-Gordon model with ad-ditional terms depending only on the total topological “charge” of the system and on the driving wave vector Q.

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 causal Green function up to second order in αr(M2), the dimensional coupling constant defined at the normalization scale M, and to all orders in β2, the dimensionless coupling constant. We show that all divergences can be removed by the renormalization of the dimensional coupling constant using the

Re-scaled Action for the sine-Gordon model. Renormalization group flows equations of the sine-Gordon model.

An effective theory for the slow modes is derived and rescaled to yield the flow equations for the model. The sine-Gordon model is discussed and analyzed within the framework of the renormalization group theory. A perturbative renormalization group procedure is described, in which the sine-Gordon field We present a renormalization group analysis for the hyperbolic sine-Gordon (sinh-Gordon) model in two dimensions. We derive the renormalization group equations based on the dimensional regularization method and the Wilson method.
