Jacobi–Lie Models and Supergravity Equations

open access: yesProgress of Theoretical and Experimental Physics
Abstract Poisson–Lie T-duality/plurality was recently generalized to Jacobi–Lie T-plurality formulated in terms of double field theory and based on Leibniz algebras given by the structure coefficients fabc, fcab, and Za, Za. We investigate three- and four-dimensional sigma models corresponding to six-dimensional Leibniz algebras with ...

On AdS4 superspace and supergravity

open access: yesJournal of High Energy Physics
In the N = 1 superspace, AdS4 supersymmetry is realized as the non-linear super coordinate transformations. The fermionic coordinates form a faithful non-linear representation of supersymmetry on their own.

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

open access: yesFortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

On the off-shell formulation of N = 2 supergravity with tensor multiplets

open access: yesJournal of High Energy Physics, 2018
We revisit the construction of N = 2 superconformal multiplets using rheonomic superspace techniques. We apply the result to the derivation of off-shell Poincaré supersymmetric models where a tensor multiplet couples to gravity and to an arbitrary number

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 ...

Supercollider signatures of supergravity models with Yukawa unification [PDF]

open access: yesPhysical Review D, 1994
We study the predictions of the simplest SU(5) grand unified model within the framework of minimal supergravity, including constraints from the radiative breaking of electroweak symmetry. As a consequence of the unification of the $b$-quark and $τ$-lepton Yukawa couplings, the top quark mass is predicted to be close to its fixed point value.

Superspace formulation of exotic supergravities in six dimensions

open access: yesJournal of High Energy Physics, 2021
We provide a linearised superfield description of the exotic non-metric N = (4, 0) supergravity in D = 6, by using a pure spinor superfield formalism. The basic field Ψ is a ghost number 2 scalar, transforming in the same R-symmetry module as the tensor ...

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.

Supersymmetry and supergravity models

open access: yesJournal of Physics G: Nuclear and Particle Physics, 1998
In this paper a review of the present status of supersymmetric (SUSY) and supergravity (SUGRA) models is presented, emphasizing the ambiguities one encounters in constructing a SUSY or SUGRA version of the standard model.
