“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 ...

Renormalization group in super-renormalizable quantum gravity

European Physical Journal C: Particles and Fields, 2018
One of the main advantages of super-renormalizable higher derivative quantum gravity models is the possibility to derive exact beta functions, by making perturbative one-loop calculations.

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‐

A note on defect stability in d = 4 − ε

Journal of High Energy Physics
We explore the space of scalar line, surface and interface defect field theories in d = 4 − ε by examining their stability properties under generic deformations.

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

General scalar renormalisation group equations at three-loop order

Journal of High Energy Physics, 2020
For arbitrary scalar QFTs in four dimensions, renormalisation group equations of quartic and cubic interactions, mass terms, as well as field anomalous dimensions are computed at three-loop order in the MS ¯ $$ \overline{\mathrm{MS}} $$ scheme. Utilising

Air Stability of Sulfide Solid Electrolytes: From Theoretical Insights to Practical Solutions

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This paper reviews research progress on the air stability of SSEs, covering their instability mechanisms and modification strategies, while outlining core challenges and future directions for practical applications. Sulfide solid electrolytes are pivotal for enabling high‐performance all‐solid‐state batteries due to their high ionic conductivity and ...

Time-Dependent Real-Space Renormalization Group Method [PDF]

Journal of Sciences, Islamic Republic of Iran, 2005
In this paper, using the tight-binding model, we extend the real-space renormalization group method to time-dependent Hamiltonians. We drive the time-dependent recursion relations for the renormalized tight-binding Hamiltonian by decimating selective ...

Gradient flows and the curvature of theory space

Journal of High Energy Physics
The metric and potential associated with the gradient property of renormalisation group flow in multiscalar models in d = 4 − ε dimensions are studied. The metric is identified with the Zamolodchikov metric of nearly marginal operators on the sphere.

Functional renormalization group flow of massive gravity

European Physical Journal C: Particles and Fields, 2020
We apply the functional renormalization group equation to a massive Fierz–Pauli action in curved space and find that, even though a massive term is a modification in the infrared sector, the mass term modifies the value of the non-gaussian fixed point in
