Functional Renormalization Group Approach to the Sine-Gordon Model
Functional Renormalization Group Approach to the Sine-Gordon Model is a scholarly work by Janos Polonyi, published in 2009 in ''Physical Review Letters''. The main subjects of the publication include physics, density matrix renormalization group, flow, quantum chromodynamics, statistical physics, holographic principle, mathematical physics, scaling, critical phenomena, sine and cosine, functional renormalization group, quantum electrodynamics, renormalization group, and renormalization. The renormalization group flow is presented for the two-dimensional sine-Gordon model within the framework of the functional renormalization group method by including the wave-function renormalization constant.
