Renormalization group analysis for thermal turbulence
International Journal of Mathematics and Mathematical Sciences, 1997 Renormalization group theory is applied to thermal turbulence. Turbulent fluxes for the flow are accounted for by repeatedly recasting the governing equations with the smallest scales represented by effective larger scales.

Non-perturbative renormalization for a renormalization group improved gauge action [PDF]
, 2001 Renormalization constants of vector ($Z_V$) and axial-vector ($Z_A$) currents are determined non-perturbatively in quenched QCD for a renormalization group improved gauge action and a tadpole improved clover quark action using the Schr\"odinger ...

Renormalization scheme dependence and renormalization group summation [PDF]
Canadian Journal of Physics, 2018 We consider logarithmic contributions to the free energy, instanton effective action, and Laplace sum rules in QCD that are a consequence of radiative corrections. Upon summing these contributions by using the renormalization group, all dependence on the renormalization scale parameter μ cancels.

Global and microlocal aspects of Dirac operators: Propagators and Hadamard states
Mathematische Nachrichten, EarlyView.Abstract We propose a geometric approach to construct the Cauchy evolution operator for the Lorentzian Dirac operator on Cauchy‐compact globally hyperbolic 4‐manifolds. We realize the Cauchy evolution operator as the sum of two invariantly defined oscillatory integrals—the positive and negative Dirac propagators—global in space and in time, with ...

The renormalization group via statistical inference
New Journal of Physics, 2015 In physics, one attempts to infer the rules governing a system given only the results of imperfect measurements. Hence, microscopic theories may be effectively indistinguishable experimentally.

Is Deep Learning a Renormalization Group Flow?
IEEE Access, 2020 Although there has been a rapid development of practical applications, theoretical explanations of deep learning are in their infancy. Deep learning performs a sophisticated coarse graining.

Five-loop anomalous dimensions of ϕ Q operators in a scalar theory with O(N) symmetry
Journal of High Energy Physics, 2022 We compute the complete Q-dependence of anomalous dimensions of traceless symmetric tensor operator ϕ Q in O(N) scalar theory to five-loop. The renormalization factors are extracted from ϕ Q → Q ϕ form factors, and the integrand of form factors are ...

The Correlated Block Renormalization Group
, 1995 We formulate the standard real-space renormalization group method in a way which takes into account the correlation between blocks. This is achieved in a dynamical way by means of operators which reflect the influence on a given block of its neighbours ...

Higher loop renormalization of a supersymmetric field theory [PDF]
, 2007 Using Dyson--Schwinger equations within an approach developed by Broadhurst and Kreimer and the renormalization group, we show how high loop order of the renormalization group coefficients can be efficiently computed in a supersymmetric model.Comment: 8 ...

Climatic Specific Energy Rating Analysis of Outdoor PV Field Data
Progress in Photovoltaics: Research and Applications, EarlyView.The study evaluates the Climatic Specific Energy Rating (CSER) of Photovoltaic device according to IEC 61853 standard series. It explores the use of long‐term PV outdoor field data in order to understand how the length and seasonality of the data acquisition period affects the reliability of the CSER parameter. It provides important insights for the PV
