Coarse Graining Spin Foam Quantum Gravity—A Review
Frontiers 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 ...

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

“ENVIRONMENTALLY FRIENDLY” RENORMALIZATION [PDF]
International Journal of Modern Physics A, 1994 We analyze the renormalization of systems whose effective degrees of freedom are described in terms of fluctuations which are “environment”-dependent. Relevant environmental parameters considered are: temperature, system size, boundary conditions and external fields.

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

QUELLE CONCEPTION DE LA RENORMALISATION DANS LE MÉTIER D’ENSEIGNANT ?
Questions Vives, 2023 This article explores the tensions between prescribed norms and teachers’ real activity through the analysis of a training program designed to support their adoption of the Narramus method, recently introduced in Geneva’s primary schools.

Phenomenological Renormalization Group Methods [PDF]
, 1999 Some renormalization group approaches have been proposed during the last few years which are close in spirit to the Nightingale phenomenological procedure. In essence, by exploiting the finite size scaling hypothesis, the approximate critical behavior of

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