The good news about the SG model is that we can do so using the standard Wilson RG momentum shell approach. Since this approach is already familiar, we only outline the main steps. 1) We treat the Gaussian part of Title: Numerical simulations of the random phase sine-Gordon model and renormalization group predictions: Authors: Lancaster, D.J. and Ruiz-Lorenzo, J.J. Abstract: Numerical simulations of the random phase sine-Gordon model suffer from strong finite size effects preventing the non-Gaussian log2 r component of the spatial correlator from following the universal infinite volume prediction. Ultraviolet renormalization was done in the frame of the Bethe Ansatz. The fractional charge appears in the model during renormalization as a repulsion beyond the cutoff. Multi-particle production cancels on mass shell.

In this paper we study the c -function of the sine-Gordon model taking explicitly into account the periodicity of the interaction potential. The integration of the c -function along trajectories of the non-perturbative renormalization group flow gives access to the central charges of the model in the fixed points.

We show that all divergences can be removed by the renormalization of the dimensional coupling constant using the Renormalization Group Theory&Sine-Gordon Model. SUMMARY OF THE LECTURES. Lecture 2.
