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.

Combining the in-medium similarity renormalization group with the density matrix renormalization group: Shell structure and information entropy [PDF]
Physics Letters B, 2023 We propose a novel many-body framework combining the density matrix renormalization group (DMRG) with the valence-space (VS) formulation of the in-medium similarity renormalization group.

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.

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 group in super-renormalizable quantum gravity [PDF]
European Physical Journal C: Particles and Fields, 2018 One of the main advantages of super-renormalizable higher derivative quantum gravity models is the possibility to derive exact beta functions, by making perturbative one-loop calculations.

Is Deep Learning a Renormalization Group Flow?
IEEE Access, 2020 Although there has been a rapid development of practical applications, theoretical explanations of deep learning are in their infancy. Deep learning performs a sophisticated coarse graining.

Laplacian renormalization group for heterogeneous networks [PDF]
Nature Physics, 2022 The renormalization group method is routinely employed in studies of criticality in many areas of physics. A framework based on a field theoretical description of information diffusion now extends this tool to the study of complex networks.

Renormalization Group Flows on Line Defects. [PDF]
Physical Review Letters, 2021 We consider line defects in d-dimensional conformal field theories (CFTs). The ambient CFT places nontrivial constraints on renormalization group (RG) flows on such line defects.

Renormalization group flow as optimal transport [PDF]
Physical Review D, 2022 We establish that Polchinski's equation for exact renormalization group flow is equivalent to the optimal transport gradient flow of a field-theoretic relative entropy.

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 ...
