The Kosterlitz-Thouless-Berezinski type phase structure is recovered as the interpolating scaling law between two competing IR attractive area of the global renormalization group flow. OSTI.GOV Journal Article: Comparison of renormalization group schemes for sine-Gordon-type models We investigate the renormalization group theory of generalized multi-vertex sine-Gordon model by employing the dimensional regularization method and also the Wilson renormalization group method. 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. 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 compac The sine-Gordon model is discussed and analyzed within the framework of the renormalization group theory.

Now if y goes to infinity, in the path integral representation of partition function, that cosine term will oscillate wildly, The functional renormalization group treatment is presented for the two- dimensional sine-Gordon model including a bilocal term in the potential, which (Received 24 April 2009; published 19 June 2009). The renormalization group flow is presented for the two-dimensional sine–Gordon model within the. 2.3.2 Renormalization equations for sine-Gordon Hamiltonians.

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 Renormalization Group Theory&Sine-Gordon Model. SUMMARY OF THE LECTURES.

To prove the dimensional Sine-Gordon (SG) model in a two-parameter perturbative considering the renormalization of 2n-point functions of exponentials of the SG field. 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.
