Exploring T‐Duality for Self‐Dual Fields

Fortschritte der Physik, Volume 72, Issue 5, May 2024.
Abstract Avatars of T‐duality within Sen's formalism for self‐dual field strengths in various dimensions are studied. This formalism is shown to naturally accommodate the T‐duality relation between Type IIA/IIB theories when compactified on a circle without the need for imposing the self‐duality constraint by hand, as is usually done. The study of this

Some recent results for SU(3) and octonions within the geometric algebra approach to the fundamental forces of nature

Mathematical Methods in the Applied Sciences, Volume 47, Issue 3, Page 1471-1491, February 2024.
Different ways of representing the group SU(3)$$ SU(3) $$ within a Geometric Algebra approach are explored. As part of this, we consider characteristic multivectors for SU(3)$$ SU(3) $$ and how these are linked with decomposition of generators into commuting bivectors. The setting for this work is within a 6d Euclidean Clifford Algebra.

Octonionic Magical Supergravity, Niemeier Lattices, and Exceptional & Hilbert Modular Forms

Fortschritte der Physik, Volume 72, Issue 2, February 2024.
Abstract The quantum degeneracies of Bogomolny‐Prasad‐Sommerfield (BPS) black holes of octonionic magical supergravity in five dimensions are studied. Quantum degeneracy is defined purely number theoretically as the number of distinct states in charge space with a given set of invariant labels.

Flux quantization on 11-dimensional superspace

Journal of High Energy Physics
Flux quantization of the C-field in 11d supergravity is arguably necessary for the (UV-)completion of the theory, in that it determines the torsion charges carried by small numbers N ≪ ∞ of M-branes.

dS vacua and the swampland

Journal of High Energy Physics, 2019
In this note we revisit some of the recent 10d and 4d arguments suggesting that the uplifting of supersymmetric AdS vacua leads to a flattening of the potential, preventing the formation of dS vacua.

Superconformal vector multiplet self-couplings and generalised Fayet-Iliopoulos terms

Physics Letters B, 2019
As an extension of the recent construction of generalised Fayet-Iliopoulos terms in N=1 supergravity given in [1], we present self-interactions for a vector multiplet coupled to conformal supergravity.

De Sitter vacua in no-scale supergravity

Journal of High Energy Physics, 2018
No-scale supergravity is the appropriate general framework for low-energy effective field theories derived from string theory. The simplest no-scale Kähler potential with a single chiral field corresponds to a compactification to flat Minkowski space ...

Aspects of supersymmetry breaking driven inflation in orbifold models

European Physical Journal C: Particles and Fields
We consider gravitationally induced corrections to inflaton potentials driven by supersymmetry breaking in a five-dimensional supergravity, compactified on a $$ S_1/Z_2 $$ S 1 / Z 2 orbifold. The supersymmetry breaking takes place on the hidden brane and
