Topological BPS charges in 10- and 11-dimensional supergravity [PDF]

open access: yes, 2010
In this thesis we construct closed expressions that correspond to the topological charges of the various BPS branes of the IIA, IIB and $D=11$ supergravity theories. These expressions are related to the structure of the SUSY algebras in curved spacetimes.

Line and surface defects in 5D $$N=2$$ N = 2 SCFT from matter-coupled F(4) gauged supergravity

open access: yesEuropean Physical Journal C: Particles and Fields
We study supersymmetric solutions of matter-coupled F(4) gauged supergravity in the forms of $$AdS_2\times S^3$$ A d S 2 × S 3 - and $$AdS_3\times S^2$$ A d S 3 × S 2 -sliced domain walls with a non-vanishing two-form field from the supergravity ...

Tessellation Groups, Harmonic Analysis on Non‐Compact Symmetric Spaces and the Heat Kernel in View of Cartan Convolutional Neural networks

open access: yesFortschritte der Physik, Volume 74, Issue 4, April 2026.
ABSTRACT In this paper, we continue the development of the Cartan neural networks programme, launched with three previous publications, by focusing on some mathematical foundational aspects that we deem necessary for our next steps forward. The mathematical and conceptual results are diverse and span various mathematical fields, but the inspiring ...

Supersymmetric $$AdS_6$$ A d S 6 black holes from ISO(3) $$\times $$ × U(1) F(4) gauged supergravity

open access: yesEuropean Physical Journal C: Particles and Fields
We study supersymmetric $$AdS_6$$ A d S 6 black holes from matter-coupled F(4) gauged supergravity coupled to four vector multiplets with $$ISO(3)\times U(1)$$ I S O ( 3 ) × U ( 1 ) gauge group. This gauged supergravity admits a maximally supersymmetric $

The DNA of Calabi–Yau Hypersurfaces

open access: yesFortschritte der Physik, Volume 74, Issue 2, February 2026.
Abstract Genetic Algorithms are implemented for triangulations of four‐dimensional reflexive polytopes, which induce Calabi–Yau threefold hypersurfaces via Batyrev's construction. These algorithms are shown to efficiently optimize physical observables such as axion decay constants or axion–photon couplings in string theory compactifications.

Purification and Recovery of Hot-Dip Galvanizing Slag via Supergravity-Induced Cake-Mode Filtration

open access: yesMetals
The elimination and retrieval of slag produced during the hot-dip galvanizing process are crucial in reducing plating defects and enhancing economic efficiency.

Janis–Newman Algorithm: Generating Rotating and NUT Charged Black Holes

open access: yesUniverse, 2017
In this review we present the most general form of the Janis–Newman algorithm. This extension allows generating configurations which contain all bosonic fields with spin less than or equal to two (real and complex scalar fields, gauge fields, metric ...

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

open access: yesFortschritte 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.

Black hole attractors and the entropy function in four- and five-dimensional N=2 supergravity [PDF]

open access: yes, 2007
Extremal black holes in theories of gravity coupled to abelian gauge fields and neutral scalars, such as those arising in the low-energy description of compactifications of string theory on Calabi-Yau manifolds, exhibit the attractor phenomenon: on the ...

On the paper “Bundle gerbes” by Michael Murray

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract The article gives a brief survey of Murray's notion of bundle gerbes as introduced in his 1996 paper published in the Journal of the London Mathematical Society, together with some of its applications.
