Impact of Quantum Gravity on the UV Sensitivity of Extremal Black Holes
Fortschritte der Physik, Volume 74, Issue 4, April 2026.ABSTRACT Recent work has revealed that extremal Kerr black holes may exhibit a sensitivity to higher‐derivative corrections to Einstein's equations, displaying singularities in the tidal forces at the horizon. However, in a purely gravitational context, this “ultraviolet sensitivity” translates into a strong dependence on the Wilson coefficients in the

On the equivalence between implicit regularization and constrained differential renormalization [PDF]
The European Physical Journal C, 2007 Constrained Differential Renormalization (CDR) and the constrained version of Implicit Regularization (IR) are two regularization independent techniques that do not rely on dimensional continuation of the space-time. These two methods which have rather distinct basis have been successfully applied to several calculations which show that they can be ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.Abstract Magmatic systems are the products of the migration and storage of compositionally evolving magmas within the solid crust. Direct computation of thermodynamic properties during magma transport remains a major challenge in multiphase‐transport modeling due to its computational cost.

Stochastic quantization, non-markovian regularization and renormalization
Nuclear Physics B, 1988 Abstract We consider the stochastic quantization of field theories, generalized to suitable non-markovian processes which can be used as an analytic ultraviolet regularization, and also to provide a new approximation scheme for computing critical exponents. We discuss the renormalization procedure for the general case, making use also of the recently

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.Abstract Joint estimation of discrete (e.g., lithology or geofluid type) and continuous (e.g., porosity, pore geometry, related connectivity) subsurface parameters represents a challenging inverse problem due to strong parameter trade‐offs, effective non‐uniqueness, and multi‐modal posterior structures.

Linear response of entanglement entropy to T T ¯ $$ T\overline{T} $$ in massive QFTs
Journal of High Energy Physics, 2023 We compute the leading correction to entanglement entropy in T T ¯ $$ T\overline{T} $$ deformed massive QFTs. We show that both for massive scalar and Dirac fermion, the leading order correction to the entanglement entropy of half space comes from the ...

A Systematic All-Orders Method to Eliminate Renormalization-Scale and Scheme Ambiguities in PQCD
, 2013 We introduce a generalization of the conventional renormalization schemes used in dimensional regularization, which illuminates the renormalization scheme and scale ambiguities of pQCD predictions, exposes the general pattern of nonconformal {\beta_i ...

Non‐Relativistic Limit of Dirac Hamiltonians With Aharonov–Bohm Fields
Studies in Applied Mathematics, Volume 156, Issue 4, April 2026.ABSTRACT We characterize the families of self‐adjoint Dirac and Schrödinger operators with Aharonov–Bohm magnetic field, and we exploit the non‐relativistic limit of infinite light speed to connect the former to the latter. The limit consists of the customary removal of the rest energy and of a suitable scaling, with the light speed, of the short‐scale

Differential Renormalization of the Wess-Zumino Model
, 1991 We apply the recently developed method of differential renormalization to the Wess-Zumino model. From the explicit calculation of a finite, renormalized effective action, the $\beta$-function is computed to three loops and is found to agree with previous
