Renormalized functional renormalization group [PDF]

open access: yesPhysics Letters B, 2018
We construct a new version of the effective average action together with its flow equation. The construction entails in particular the consistency of fluctuation field and background field equations of motion, even for finite renormalization group scales.

The analytic renormalization group

open access: yesNuclear Physics B, 2016
Finite temperature Euclidean two-point functions in quantum mechanics or quantum field theory are characterized by a discrete set of Fourier coefficients Gk, k∈Z, associated with the Matsubara frequencies νk=2πk/β.

Holographic Renormalization Group [PDF]

open access: yesProgress of Theoretical Physics, 2002
The holographic renormalization group (RG) is reviewed in a self-contained manner. The holographic RG is based on the idea that the radial coordinate of a space-time with asymptotically AdS geometry can be identified with the RG flow parameter of the ...

Renormalization group and divergences [PDF]

open access: yesJournal of Statistical Physics, 2014
Application of asymptotic freedom to the ultraviolet stability in Euclidean quantum field theories is revisited and illustrated through the hierarchical model making also use of a few technical developments that followed the original works of Wilson on ...

Gutzwiller Renormalization Group

open access: yesPhysical Review B, 2015
We develop a variational scheme called "Gutzwiller renormalization group" (GRG), which enables us to calculate the ground state of Anderson impurity models (AIM) with arbitrary numerical precision.

Renormalization Group Flow in CDT [PDF]

open access: yesClassical and Quantum Gravity, 2014
We perform a first investigation of the coupling constant flow of the nonperturbative lattice model of four-dimensional quantum gravity given in terms of Causal Dynamical Triangulations (CDT).

Renormalization group methods

open access: bronzeAdvances in Mathematics, 1975
AbstractAn especially intractable breed of problems in physics involves those with very many or an infinite number of degrees of freedom and in addition involve “renormalization.” Renormalization is explained as the existence of very many length or energy scales of importance in the physics of the problem. The renormalization group approach is a way of

Renormalization group and universality [PDF]

open access: yesPhysical Review D, 1995
It is argued that universality is severely limited for models with multiple fixed points. As a demonstration the renormalization group equations are presented for the potential and the wave function renormalization constants in the $O(N)$ scalar field theory.
