Generalized covariant entropy bound in Einstein gravity with quadratic curvature corrections
Journal of High Energy PhysicsWe explore the generalized covariant entropy bound in the theory where Einstein gravity is perturbed by quadratic curvature terms, which can be viewed as the first-order quantum correction to Einstein gravity.

Astronomische Nachrichten, EarlyView.ABSTRACT We investigate the effects of a minimal measurable length on neutron stars, within the quantum hadrodynamics (QHD‐I) model modified by the Generalized Uncertainty Principle (GUP). Working in a deformed Poisson algebra framework, we incorporate GUP effects via a time‐invariant transformation of the phase space volume, effectively reducing the ...

The Value Chain of Sustainable Dual Carbon Sodium Ion Capacitors
Batteries &Supercaps, EarlyView.Sodium‐ion capacitors (SICs) bridge the energy‐power gap between batteries and supercapacitors, offering sustainable and scalable energy storage solutions. This review provides a 360‐degree perspective on SIC technology, covering material choices, presodiation strategies, manufacturing challenges, applications and life cycle assessment to ensure ...

A path integral formula of quantum gravity emergent from entangled local structures
Journal of High Energy PhysicsWe couple to group field theory (GFT) a scalar field that encodes the entanglement between manifold sites. The scalar field provides a relational clock that enables the derivation of the Hamiltonian of the system from the GFT action.

‘Let's talk about the weather’: The activist curriculum and global climate change education
British Educational Research Journal, EarlyView.Abstract Activist movements have garnered significant global attention on a range of sustainability issues, often involving collectives of citizens coming together. Invoked is the idea of citizens informed to act, emerging not from a common‐sense understanding of everyday life, but rather from a deep political understanding of the world—one that is ...

Form factors, spectral and Källén-Lehmann representation in nonlocal quantum gravity
Journal of High Energy PhysicsWe discuss the conical region of convergence of exponential and asymptotically polynomial form factors and their integral representations. Then, we calculate the spectral representation of the propagator of nonlocal theories with entire form factors, in ...

Tackling ignorance about law in human rights education
British Educational Research Journal, EarlyView.Abstract This paper aims to unpack potential reasons why law and legal knowledge—despite its apparent importance and value in teaching and learning about human rights—appears to be largely conspicuous by its absence in human rights education (HRE) in schooling.

The semi-classical saddles in three-dimensional gravity via holography and mini-superspace approach [PDF]
arXivWe determine the complex geometries dual to the semi-classical saddles in three-dimensional gravity with positive or negative cosmological constant. We examine the semi-classical saddles in Liouville field theory and interpret them in terms of gravity theory.
