Mutual information, neural networks and the renormalization group [PDF]

open access: yesNature Physics, 2017
Physical systems differing in their microscopic details often display strikingly similar behaviour when probed at macroscopic scales. Those universal properties, largely determining their physical characteristics, are revealed by the powerful ...

B physics beyond the Standard Model at one loop: complete renormalization group evolution below the electroweak scale [PDF]

open access: yesJournal of High Energy Physics, 2017
General analyses of B-physics processes beyond the Standard Model require accounting for operator mixing in the renormalization-group evolution from the matching scale down to the typical scale of B physics.

Scale-invariant Feature Extraction of Neural Network and Renormalization Group Flow [PDF]

open access: yesPhysical Review E, 2018
Theoretical understanding of how a deep neural network (DNN) extracts features from input images is still unclear, but it is widely believed that the extraction is performed hierarchically through a process of coarse graining.

Renormalization group approach to spontaneous stochasticity

open access: yesPhysical Review Research, 2020
We develop a theoretical approach to “spontaneous stochasticity” in classical dynamical systems that are nearly singular and weakly perturbed by noise. This phenomenon is associated with a breakdown in the uniqueness of solutions for fixed initial data ...

Renormalization Group in Non-Relativistic Quantum Statistics [PDF]

open access: yesEPJ Web of Conferences, 2020
Dynamic behaviour of a boson gas near the condensation transition in the symmetric phase is analyzed with the use of an effective large-scale model derived from time-dependent Green functions at finite temperature.

Renormalization group fixed points of foliated gravity-matter systems [PDF]

open access: yesJournal of High Energy Physics, 2017
We employ the Arnowitt-Deser-Misner formalism to study the renormalization group flow of gravity minimally coupled to an arbitrary number of scalar, vector, and Dirac fields. The decomposition of the gravitational degrees of freedom into a lapse function,

Renormalization group theory of earthquakes [PDF]

open access: yesNonlinear Processes in Geophysics, 1996
We study theoretically the physical origin of the proposed discrete scale invariance of earthquake processes, at the origin of the universal log-periodic corrections to scaling, recently discovered in regional seismic activity ...

Renormalization Group evolution from on-shell SMEFT

open access: yesJournal of High Energy Physics, 2021
We describe the on-shell method to derive the Renormalization Group (RG) evolution of Wilson coefficients of high dimensional operators at one loop, which is a necessary part in the on-shell construction of the Standard Model Effective Field Theory ...

Critical phenomena and functional renormalization group

open access: yesHe jishu, 2023
Recent progress in studies on quantum chromodynamics (QCD) phase transition and related critical phenomena within the functional renormalization group (fRG) approach were reviewed, including the nonperturbative critical exponents and baryon number ...

Novel demonstration of the renormalization group invariance of the fixed-order predictions using the principle of maximum conformality and the C -scheme coupling [PDF]

open access: yesPhysical Review D, 2018
As a basic requirement of the renormalization group invariance, any physical observable must be independent of the choice of both the renormalization scheme and the initial renormalization scale.
