N=2 Supersymmetry and U(1)-Duality
Physical Review D - Particles, Fields, Gravitation and Cosmology, 2012 Understanding the consequences of the E_{7(7)} duality on the UV properties of N=8 supergravity requires unravelling when and how duality-covariant actions can be constructed so as to accommodate duality-invariant counter-terms. For non-supersymmetric abelian gauge theories exhibiting U(1)-duality, with and without derivative couplings, it was shown ...

Topological correlators and surface defects from equivariant cohomology
Journal of High Energy Physics, 2020 We find a one-dimensional protected subsector of N $$ \mathcal{N} $$ = 4 matter theories on a general class of three-dimensional manifolds. By means of equivariant localization we identify a dual quantum mechanics computing BPS correlators of the ...

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

Review of lattice supersymmetry and gauge-gravity duality [PDF]
International Journal of Modern Physics A, 2015 We review the status of recent investigations on validating the gauge-gravity duality conjecture through numerical simulations of strongly coupled maximally supersymmetric thermal gauge theories. In the simplest setting, the gauge-gravity duality connects systems of D0-branes and black hole geometries at finite temperature to maximally supersymmetric ...

A “Lagrangian” for the E 7 superconformal theory
Journal of High Energy Physics, 2018 We find an N=1 $$ \mathcal{N}=1 $$ gauge theory that flows to the rank-one N=2 $$ \mathcal{N}=2 $$ superconformal field theory with E 7 flavor symmetry.

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.

Nilpotent N=1 $$ \mathcal{N}=1 $$ tensor multiplet
Journal of High Energy Physics, 2018 We propose a nilpotent N=1 $$ \mathcal{N}=1 $$ tensor multiplet describing two fields, which are the Goldstino and the axion, the latter being realised in terms of the field strength of a gauge two-form.

Fortschritte der Physik, Volume 72, Issue 2, February 2024.Abstract The string theory landscape may include a multitude of ultraviolet embeddings of the Standard Model, but identifying these has proven difficult due to the enormous number of available string compactifications. Genetic Algorithms (GAs) represent a powerful class of discrete optimisation techniques that can efficiently deal with the immensity of

Duality after Supersymmetry Breaking
, 1998 Starting with two supersymmetric dual theories, we imagine adding a chiral perturbation that breaks supersymmetry dynamically. At low energy we then get two theories with soft supersymmetry-breaking terms that are generated dynamically. With a canonical Kahler potential, some of the scalars of the "magnetic" theory typically have negative mass-squared,

Journal of High Energy Physics, 2017 We calculate the instanton partition function of the four-dimensional N = 2 ⋆ $$ \mathcal{N}={2}^{\star } $$ SU(N) gauge theory in the presence of a generic surface operator, using equivariant localization.
