Scalar-Tensor gravity with system-dependent potential and its relation with Renormalization Group extended General Relativity

, 2015
We show that Renormalization Group extensions of the Einstein-Hilbert action for large scale physics are not, in general, a particular case of standard Scalar-Tensor (ST) gravity.

Redefining Graphene Oxide: The Role of Organosulfate Groups in Charging Dynamics and Colloidal Stability

Small Structures, EarlyView.
This work redefines graphene oxide (GO) as a 2D polyelectrolyte by revealing the dominant role of organosulfate groups in its charging dynamics and stability. Challenging conventional models, the findings offer a predictive framework for the design and optimization of GO‐based membranes, electrodes, and nanomaterials across diverse technologies ...

Similarity renormalization group evolution of N N interactions within a subtractive renormalization scheme

EPJ Web of Conferences, 2010
We apply the similarity renormalization group (SRG) approach to evolve a nucleon-nucleon (N N) interaction in leading-order (LO) chiral effective field theory (ChEFT), renormalized within the framework of the subtracted kernel method (SKM).

Scalar kinetic mixing and the renormalization group

Physics Letters B, 2019
Quantum field theories containing scalar fields with equal quantum numbers allow for a mixed kinetic term in the Lagrangian. It has been argued that this mixing must be taken into consideration when performing renormalization group (RG) analyses of such ...

Towards c=0 Flows

, 1994
We discuss some implications of the gravitational dressing of the renormalization group for conformal field theories perturbed by relevant operators. The renormalization group flows are defined with respect to the dilatation operator associated with the $

The renormalization group equations revisited [PDF]

International Journal of Modern Physics A, 2018
Starting from a well-defined local Lagrangian, we analyze the renormalization group equations in terms of the two different arbitrary scales associated with the regularization procedure and with the physical renormalization of the bare parameters, respectively.

Tailoring the Electron Density of Functional Groups for Controlled Charge Transfer in SWCNTs

Small Structures, EarlyView.
This article presents a molecular design strategy enabling precise charge transfer control in single‐walled carbon nanotubes at the single‐particle level. Through systematic assembly of aniline‐methoxy units on triazine anchors, tunable electron donation and withdrawal are achieved, shifting the Fermi level up or down over hundreds of ...

Developmental and epileptic encephalopathy with spike–wave activation in sleep: From the ‘functional ablation’ model to a neurodevelopmental network perspective

Developmental Medicine &Child Neurology, EarlyView.
The pathophysiology of D/EE‐SWAS has traditionally been conceptualized as a cause–effect continuum wherein genetic and environmental factors influence brain morphology, subsequently inducing electrical abnormalities during sleep, resulting in cognitive impairment.
