Monopoles, Clarified

Fortschritte der Physik, Volume 74, Issue 3, March 2026.
ABSTRACT We propose a manifestly duality‐invariant, Lorentz‐invariant, and local action to describe quantum electrodynamics in the presence of magnetic monopoles that derives from Sen's formalism. By employing field strengths as the dynamical variables, rather than potentials, this formalism resolves longstanding ambiguities in prior frameworks.

The holographic dual to supergravity instantons in AdS5 × S5 /ℤk

Journal of High Energy Physics, 2019
We investigate the holographic dual to supergravity instanton solutions in AdS5 × S5 / ℤk, which are described entirely in terms of geodesics on the AdS moduli space.

Coordinate‐ and Spacetime‐Independent Quantum Physics

Annalen der Physik, Volume 538, Issue 1, January 2026.
This article studies in the framework of quantum field theory in curved spacetime, if there exists a single zero‐rank‐tensor solution of a Klein‐Gordon PDE, being valid at once for the depicted spacetimes. The answer is shown to be affirmative, even for a class of such solutions having the standard applications in particle physics. ABSTRACT The concept

Analysis of Ward identities in supersymmetric Yang–Mills theory

European Physical Journal C: Particles and Fields, 2018
In numerical investigations of supersymmetric Yang–Mills theory on a lattice, the supersymmetric Ward identities are valuable for finding the critical value of the hopping parameter and for examining the size of supersymmetry breaking by the lattice ...

Grey‐Body Factors and Absorption Cross‐Sections of Scalar and Dirac Fields in the Vicinity of Dilaton‐De Sitter Black Hole

Fortschritte der Physik, Volume 74, Issue 1, January 2026.
Abstract The propagation of a massive scalar field and a massless Dirac field in the geometry of a dilaton–de Sitter black hole is investigated. Starting from the covariant perturbation equations, the corresponding effective potentials are presented and their dependence on the dilaton charge, field mass, and cosmological constant is analyzed. Using the

Spectrum of large N glueballs: holography vs lattice

Journal of High Energy Physics, 2022
Recently there has been a notable progress in the study of glueball states in lattice gauge theories, in particular extrapolating their spectrum to the limit of large number of colors N.

Simultaneous Bosonic and Fermionic T‐Dualization of the Type II Superstring Theory—Buscher Approach and Double Space Representation

Fortschritte der Physik, Volume 74, Issue 1, January 2026.
Abstract In this article I consider type II superstring in the pure spinor formulation with constant background fields in the context of T‐dualization. First, I prove that bosonic and fermionic T‐dualization commute using already known T‐dual transformation laws for bosonic and fermionic T‐dualization.

Neutrino Magnetic Moment in the Doublet‐Singlet Leptoquark Model

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.
The transition magnetic moment for Majorana neutrinos is studied in a simple extension of the Standard Model. This extension incorporates two scalar Leptoquarks S1 and R~2 with quantum numbers 3¯,113,/ and (3, 2, 1/6), respectively. It is found that these Leptoquarks generate a sizable transition magnetic moment, particularly when the quark bottom is ...

Low-energy effective action in 5D,N=2 supersymmetric gauge theory

Nuclear Physics B, 2019
We construct N=2 supersymmetric low-energy effective action of 5D,N=2 supersymmetric Yang–Mills (SYM) theory in 5D,N=1 harmonic superspace. It is obtained as a hypermultiplet completion of the leading Wln⁡W-term in the N=1 SYM low-energy effective action

Structural Analysis of Homomorphisms and Derivations in C∗‐Ternary Algebras Related to Additive–Quadratic Functional Equations

International Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.
In this paper, we study algebraic structures associated with homomorphisms and derivations, which play a significant role in physics and engineering. Our main focus is on the Ulam–Hyers stability of homomorphism and derivation structures related to a class of two‐dimensional additive–quadratic functional equations in C∗‐ternary algebras.
