The analytic renormalization group [PDF]
Nuclear 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.

Renormalized functional renormalization group [PDF]
Physics 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.

Global Renormalization Group [PDF]
Physical Review D, 1997 The motivation and the challenge in applying the renormalization group for systems with several scaling regimes is briefly outlined. The four dimensional $\phi^4$ model serves as an example where a nontrivial low energy scaling regime is identified in ...

Renormalization Group Therapy [PDF]
Physical Review D, 2007 We point out a general problem with the procedures commonly used to obtain improved actions from MCRG decimated configurations. Straightforward measurement of the couplings from the decimated configurations, by one of the known methods, can result into ...

Renormalization group and divergences [PDF]
Journal 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 ...

Renormalization Group and Universality [PDF]
Physical 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 ...

From Renormalization Group Flows to Cosmology [PDF]
Frontiers in Physics, 2020 According to the asymptotic-safety conjecture, the gravitational renormalization group flow features an ultraviolet-attractive fixed point that makes the theory renormalizable and ultraviolet complete.

Gutzwiller Renormalization Group
Physical 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 theory of molecular dynamics [PDF]
Scientific Reports, 2021 Large scale computation by molecular dynamics (MD) method is often challenging or even impractical due to its computational cost, in spite of its wide applications in a variety of fields.

Holographic Renormalization Group [PDF]
Progress 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 ...
