Convergence of Nonperturbative Approximations to the Renormalization Group. [PDF]

open access: yesPhysical Review Letters, 2019
We provide analytical arguments showing that the "nonperturbative" approximation scheme to Wilson's renormalization group known as the derivative expansion has a finite radius of convergence. We also provide guidelines for choosing the regulator function

Entanglement entropy: Holography and renormalization group [PDF]

open access: yesReviews of Modern Physics, 2018
In this review the entanglement and Renyi entropies in quantum field theory are described from different points of view, including the perturbative approach and holographic dualities.

Anisotropic tensor renormalization group [PDF]

open access: yes, 2019
We propose a new tensor renormalization group algorithm, Anisotropic Tensor Renormalization Group (ATRG), for lattice models in arbitrary dimensions.

Rapidity Renormalization Group

open access: yesPhysical Review Letters, 2012
We introduce a systematic approach for the resummation of perturbative series which involves large logarithms not only due to large invariant mass ratios but large rapidities as well. A series of this form can appear in a variety of gauge theory observables.

Machine learning holographic mapping by neural network renormalization group [PDF]

open access: yesPhysical Review Research, 2019
The exact holographic mapping (EHM) provides an explicit duality map between a conformal field theory (CFT) configuration and a massive field propagating on an emergent classical geometry. However, designing the optimal holographic mapping is challenging.

Neural Network Renormalization Group [PDF]

open access: yesPhysical Review Letters, 2018
We present a variational renormalization group (RG) approach based on a reversible generative model with hierarchical architecture. The model performs hierarchical change-of-variables transformations from the physical space to a latent space with reduced

Asymptotic freedom and higher derivative gauge theories

open access: yesJournal of High Energy Physics, 2021
The ultraviolet completion of gauge theories by higher derivative terms can dramatically change their behavior at high energies. The requirement of asymptotic freedom imposes very stringent constraints that are only satisfied by a small family of higher ...

Analytically Solvable Renormalization Group for the Many-Body Localization Transition. [PDF]

open access: yesPhysical Review Letters, 2018
We introduce a simple, exactly solvable strong-randomness renormalization group (RG) model for the many-body localization (MBL) transition in one dimension.

Towards general scalar-Yukawa renormalisation group equations at three-loop order

open access: yesJournal of High Energy Physics, 2021
For arbitrary four-dimensional quantum field theories with scalars and fermions, renormalisation group equations in the MS ¯ $$ \overline{\mathrm{MS}} $$ scheme are investigated at three-loop order in perturbation theory.
