Coarse Graining Spin Foam Quantum Gravity—A Review

open access: yesFrontiers in Physics, 2020
In quantum gravity, we envision renormalization as the key tool for bridging the gap between microscopic models and observable scales. For spin foam quantum gravity, which is defined on a discretization akin to lattice gauge theories, the goal is to ...

Renormalization aspects of N=1 Super Yang-Mills theory in the Wess-Zumino gauge [PDF]

open access: yes, 2014
The renormalization of N=1 Super Yang-Mills theory is analysed in the Wess-Zumino gauge, employing the Landau condition. An all orders proof of the renormalizability of the theory is given by means of the Algebraic Renormalization procedure.

Multigrid renormalization [PDF]

open access: yesJournal of Computational Physics, 2018
We combine the multigrid (MG) method with state-of-the-art concepts from the variational formulation of the numerical renormalization group. The resulting MG renormalization (MGR) method is a natural generalization of the MG method for solving partial differential equations.

A measure of identifying influential community based on the state of critical functionality

open access: yesMathematical Biosciences and Engineering, 2020
As an open issue, the measure of community influential is no uniform standard, how to measure the influence of community has attracted extensive attention. This paper proposed a quantitative measure to identify the influence of community.

Renormalization group and nonequilibrium action in stochastic field theory [PDF]

open access: yes, 2002
We investigate the renormalization group approach to nonequilibrium field theory. We show that it is possible to derive nontrivial renormalization group flow from iterative coarse graining of a closed-time-path action.

Layer-Wise Relevance Propagation for Neural Networks with Local Renormalization Layers [PDF]

open access: yesInternational Conference on Artificial Neural Networks, 2016
Layer-wise relevance propagation is a framework which allows to decompose the prediction of a deep neural network computed over a sample, e.g. an image, down to relevance scores for the single input dimensions of the sample such as subpixels of an image.

Renormalization Mass Scale and Scheme Dependence in the Perturbative Contribution to Inclusive Semileptonic $b$ Decays

open access: yes, 2021
We examine the perturbative calculation of the inclusive semi-leptonic decay rate $\Gamma$ for the $b$-quark, using mass-independent renormalization.

Dynamic and Renormalization-Group Extensions of the Landau Theory of Critical Phenomena

open access: yesEntropy, 2020
We place the Landau theory of critical phenomena into the larger context of multiscale thermodynamics. The thermodynamic potentials, with which the Landau theory begins, arise as Lyapunov like functions in the investigation of the relations among ...
