General quartic β-function at three loops

Journal of High Energy Physics
We determine the three-loop MS ¯ $$ \overline{\textrm{MS}} $$ quartic β-function for the most general renormalisable four-dimensional theories. A general parametrisation of the β-function is compared to known β-functions for specific theories to fix all ...

FIRE‐GNN: Force‐Informed, Relaxed Equivariance Graph Neural Network for Rapid and Accurate Prediction of Surface Properties

Advanced Intelligent Discovery, EarlyView.
This study introduces FIRE‐GNN, a force‐informed, relaxed equivariant graph neural network for predicting surface work functions and cleavage energies from slab structures. By incorporating surface‐normal symmetry breaking and machine learning interatomic potential‐derived force information, the approach achieves state‐of‐the‐art accuracy and enables ...

Renormalization group procedure for potential −g/r2

Physics Letters B, 2018
Schrödinger equation with potential −g/r2 exhibits a limit cycle, described in the literature in a broad range of contexts using various regularizations of the singularity at r=0. Instead, we use the renormalization group transformation based on Gaussian

A priori bounds for the generalised parabolic Anderson model

Communications on Pure and Applied Mathematics, EarlyView.
Abstract We show a priori bounds for solutions to (∂t−Δ)u=σ(u)ξ$(\partial _t - \Delta) u = \sigma (u) \xi$ in finite volume in the framework of Hairer's Regularity Structures [Invent Math 198:269–504, 2014]. We assume σ∈Cb2(R)$\sigma \in C_b^2 (\mathbb {R})$ and that ξ$\xi$ is of negative Hölder regularity of order −1−κ$- 1 - \kappa$ where κ<κ¯$\kappa <

“Train and Hope”: The Role of Restorative Justice Coordinators in Sustaining a Culture of Care in Schools

Conflict Resolution Quarterly, EarlyView.
ABSTRACT This article examines the role of restorative justice coordinators in supporting teachers and schools in adopting a whole‐school approach to restorative justice in education. Coordinators are often tasked with implementing a train‐and‐hope model, in which they receive initial training in restorative justice but are largely left unsupported ...

Quenching the Hubbard Model: Comparison of Nonequilibrium Green's Function Methods

Contributions to Plasma Physics, EarlyView.
ABSTRACT We benchmark nonequilibrium Green's function (NEGF) approaches for interaction quenches in the half‐filled Fermi–Hubbard model in one and two dimensions. We compare fully self‐consistent two‐time Kadanoff–Baym equations (KBE), the generalized Kadanoff–Baym ansatz (GKBA), and the recently developed NEGF‐based quantum fluctuations approach (NEGF‐

Dual‐Molten‐Salt Etching Strategy Enables Built‐in Electric Field in Mo‐MXene/NiFeSe Heterostructure for Superior OER Performance

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A dual‐molten‐salt etching strategy was employed to construct a built‐in electric field in the Mo‐MXene/NiFeSe heterostructure to achieve excellent oxygen evolution reaction. Transition metal selenides have emerged as potential catalysts for the oxygen evolution reaction, yet their practical implementation faces two fundamental challenges: irreversible

Wilsonian renormalization group versus subtractive renormalization in effective field theories for nucleon–nucleon scattering

Nuclear Physics B, 2017
We compare the subtractive renormalization and the Wilsonian renormalization group approaches in the context of an effective field theory for the two-nucleon system. Based on an exactly solvable model of contact interactions, we observe that the standard

Estimation of the GCV of Coal Using Real‐Time Plant Data

Energy Science &Engineering, EarlyView.
ABSTRACT Online or real‐time strategies of estimating the gross calorific value (GCV) of coal are still not fully explored in academic literature, even though both conventional and sophisticated offline methods for estimating the GCV are well described.

Relativistic low-momentum interactions from renormalization group

Physics Letters B
The relativistic Vlowk is developed from a renormalization group method for the first time, to provide softened NN interactions for relativistic abinitio calculations. Starting from a given bare NN interaction, the renormalization group method eliminates
