Asymptotic normalization properties and mass independent renormalization group functions [PDF]

Helv.Phys.Acta 67 (1994) 424-435, 1994
Mass independent renormalization group functions in massive theories are related to normalization properties of the Green functions in the asymptotic region, where mass effects are neglected. In this special form the renormalization group invariance is restricted to the asymptotic region and consequently mass effects cannot be recoverd by a integration

Comparative proteomics analysis of root and nodule mitochondria of soybean

Plant, Cell &Environment, EarlyView.
Abstract Legumes perform symbiotic nitrogen fixation through rhizobial bacteroids housed in specialised root nodules. The biochemical process is energy‐intensive and consumes a huge carbon source to generate sufficient reducing power. To maintain the symbiosis, malate is supplied by legume nodules to bacteroids as their major carbon and energy source ...

Evidence for a novel shift-symmetric universality class from the functional renormalization group

Physics Letters B, 2023
Wetterich's equation provides a powerful tool for investigating the existence and universal properties of renormalization group fixed points exhibiting quantum scale invariance.

Renormalized expansion for matrix models [PDF]

arXiv, 1994
Matrix models of 2d quantum gravity coupled to matter field are investigated by the renormalized perturbational method, in which the matrix model Hamiltonian is represented by the equivalent vector model. By the saddle point method, the renormalization group beta-function is obtained in the successive approximation.

Impact of topology in foliated quantum Einstein gravity

European Physical Journal C: Particles and Fields, 2017
We use a functional renormalization group equation tailored to the Arnowitt–Deser–Misner formulation of gravity to study the scale dependence of Newton’s coupling and the cosmological constant on a background spacetime with topology $$S^1 \times S^d$$ S ...

Spectral functions in holographic renormalization group flows [PDF]

Journal of High Energy Physics, 2009
The spectrum of two-point functions in a holographic renormalization group flow from an ultraviolet (UV) to an infrared (IR) conformal fixed point is necessarily continuous. For a toy model, the spectral function does not only show the expected UV and IR behaviours, but other interesting features such as sharp peaks and oscillations in the UV.

On the deep‐water and shallow‐water limits of the intermediate long wave equation from a statistical viewpoint

Transactions of the London Mathematical Society, Volume 12, Issue 1, December 2025.
Abstract We study convergence problems for the intermediate long wave (ILW) equation, with the depth parameter δ>0$\delta > 0$, in the deep‐water limit (δ→∞$\delta \rightarrow \infty$) and the shallow‐water limit (δ→0$\delta \rightarrow 0$) from a statistical point of view.

Stochastic formulation of the renormalization group: supersymmetric structure and topology of the space of couplings

, 2004
The exact or Wilson renormalization group equations can be formulated as a functional Fokker-Planck equation in the infinite-dimensional configuration space of a field theory, suggesting a stochastic process in the space of couplings.

Heterostructured Electrocatalysts: from Fundamental Microkinetic Model to Electron Configuration and Interfacial Reactive Microenvironment

Advanced Materials, Volume 37, Issue 15, April 16, 2025.
Heterostructures have emerged as advanced electrocatalysts to convert earth‐abundant simple molecules into high‐value‐added products. On the basis of atomistic understanding to accelerate the electrochemical processes, the architecture of heterostructured electrocatalysts is comprehensively discussed from the point of view of modulating electronic ...

Optimal renormalization and the extraction of strange quark mass from semi-leptonic $τ$-decay [PDF]

arXiv, 2017
We employ optimal renormalization group analysis to semi-leptonic $\tau$-decay polarization functions and extract the strange quark mass from their moments measured by the ALEPH and OPAL collaborations. The optimal renormalization group makes use of the renormalization group equation of a given perturbation series which then leads to closed form sum of
