Automatic differentiable numerical renormalization group

Physical Review Research, 2022
Machine learning techniques have recently gained prominence in physics, yielding a host of new results and insights. One key concept is that of backpropagation, which computes the exact gradient of any output of a program with respect to any input.

Neural Monte Carlo renormalization group

Physical Review Research, 2021
The key idea behind the renormalization group (RG) transformation is that properties of physical systems with very different microscopic makeups can be characterized by a few universal parameters.

Higher logarithms and ε-poles for the MS-like renormalization prescriptions

Journal of High Energy Physics, 2023
We consider a version of dimensional regularization (reduction) in which the dimensionful regularization parameter Λ is in general different from the renormalization scale μ.

Ward-constrained melonic renormalization group flow

Physics Letters B, 2020
In recent years, interesting investigations of the nonperturbative renormalization group equations for tensorial group field theories have been performed in the truncation method, while completely discarding the Ward identities from their analysis.

Leading all-loop quantum contribution to the effective potential in general scalar field theory

Journal of High Energy Physics, 2023
The RG equation for the effective potential in the leading log (LL) approximation is constructed which is valid for an arbitrary scalar field theory in 4 dimensions.

The Holographic Renormalization Group [PDF]

Fortschritte der Physik, 2001
In this lecture, we review the derivation of the holographic renormalization group given in hep-th/9912012. Some extra background material is included, and various applications are discussed.
