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
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.

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.

Renormalization scheme dependence and renormalization group summation [PDF]
Canadian Journal of Physics, 2018 We consider logarithmic contributions to the free energy, instanton effective action, and Laplace sum rules in QCD that are a consequence of radiative corrections. Upon summing these contributions by using the renormalization group, all dependence on the renormalization scale parameter μ cancels.

Interpolation Formulas for Asymptotically Safe Cosmology
Universe, 2023 Simple interpolation formulas are proposed for the description of the renormalization group (RG) scale dependences of the gravitational couplings in the framework of the 2-parameters Einstein-Hilbert (EH) theory of gravity and applied to a simple ...
