Confinement in a finite duality cascade
A bstract: We provide several consistency checks of confining dynamics in a recently conjectured holographic dual of a four-dimensional $$ \mathcal{N} $$ = 1 supersymmetric gauge theory that flows from a conformal manifold in the UV to a finite set of isolated, fully gapped vacua in the IR. This is obtained by considering D3-branes at the conifold singularity in the presence of an O7-plane, leading to a background where all supergravity fields have a non-trivial profile. We compute holographically the expectation value of a Wilson loop in the fundamental representation and show that it obeys an area law. We then construct the domain walls which interpolate between different vacua in terms of D5-branes wrapping a compact three-cycle of the internal manifold. Their dynamics is governed by the (2+1)-dimensional $$ \mathcal{N} $$ = 1 Yang-Mills-Chern-Simons theory predicted by field theory arguments, that reduces in the deep infrared to a TQFT whose inflow action correctly reproduces the mixed anomaly of the four-dimensional theory. Finally, we argue that, unlike in previous models in the literature, axionic strings are unstable in this background. This implies that the corresponding massless axion that would couple to them is absent, in agreement with the fact that the vacua are fully gapped.- 9 July 2026

Cluster structures, orientifolds of brane tilings and higher laminations
Structures amassées, orientifolds de modèles de dimères et laminations supérieures: Les algèbres et variétés amassées se manifestent naturellement dans divers champs de la physique mathématique, comme la théorie de Teichmüller de rang supérieur et l'étude des modèles de dimères. D'une part, on étudie la généralisation des laminations de Thurston aux espaces de Teichmüller de rang supérieur correspondant à des groupes réels déployés. Cela conduit notamment à l'introduction de théories topologiques des champs quantiques liées aux algèbres de Iwahori-Hecke des groupes de Coxeter finis. Celles-là associent un polynôme de Laurent entier à chaque surface épointée de type fini. D'autre part, les modèles de dimères nous permettent de prouver l'existence d'une complétion ultraviolette stable du modèle SU(5) de brisure dynamique de supersymétrie. On dérive de plus des résultats généraux quant à l'existence d'anomalies de jauge sur des D-branes transverses à des orientifolds de singularités Calabi-Yau affines toriques. Enfin, on donne un sens physique aux modèles de dimères sur la bouteille de Klein. Par ailleurs, les deux parties introductives de ce manuscrit présentent de manière pédagogique la théorie de Teichmüller de rang supérieur de Fock et Goncharov, puis les modèles de dimères en théorie des cordes ainsi que leur emploi dans l'étude des correspondances holographiques.

Global variants of $ \mathcal{N} $ = 1* theories and Calogero-Moser systemsGlobal variants of four-dimensional gauge theories are specified by their spectrum of genuine Wilson-’t Hooft line operators. The choice of global variant has significant consequences when spacetime is taken to be ℝ 3 × S 1. We focus on $$ \mathcal{N} $$ = 1* theories, which are closely connected to twisted elliptic Calogero-Moser systems. We establish, on general grounds, how this gauge-theoretic topological data manifests itself on the integrable system side by introducing a notion of global variants for complex many-body integrable systems associated with Lie algebras. Focusing on $$ \mathcal{N} $$ = 1* theories of type A and B 2, we elucidate the implications for the structure of gapped vacua, the emergent (generalized) symmetries realized in each vacuum, and the action of spontaneously broken modular invariance.- 26 August 2025

Inherited non-invertible duality symmetries in quiver SCFTs
We revisit the construction of the duality group for $$\mathcal{N}$$ = 2 $${\widehat{A}}_{n}$$ -shaped quivers SCFTs and generalize it to the previously unexplored case of $${\widehat{D}}_{n}$$ -shaped quivers. We then provide a systematic description of non-invertible duality symmetries in both classes. Furthermore, we characterize the $$\mathcal{N}$$ = 1 mass deformations of these theories that preserve such symmetries, thereby identifying a large class of $$\mathcal{N}$$ = 1 SCFTs with non-invertible duality symmetries inherited from their parent $$\mathcal{N}$$ = 2 theories.- 24 June 2025

One-form symmetries in $\mathcal{N} = 3$ S-foldsWe classify the global one-form symmetries for non-Lagrangian \mathcal{N}=3 ???? = 3 SCFTs that arise by the action of S S -fold projections on D3-branes. Such a classification is dictated, on a generic point of the Coulomb branch, by probing the charge spectrum of (p, q) ( p , q ) -strings in the brane setup. The charge lattice of lines is then obtained by finding the ones that are genuine modulo screening by dynamical particles. The one-form symmetries are then extracted from the maximal sub-lattices of mutually local lines. We further comment on the existence of non-invertible symmetries for some of these \mathcal{N}=3 ???? = 3 SCFTs.

Topological quantum field theories from Hecke algebras
We construct one-dimensional non-commutative topological quantum field theories (TQFTs), one for each Hecke algebra corresponding to a finite Coxeter system. These TQFTs associate an invariant to each ciliated surface, which is a Laurent polynomial for punctured surfaces. There is a graphical way to compute the invariant using minimal colored graphs. We give explicit formulas in terms of the Schur elements of the Hecke algebra and prove positivity properties for the invariants when the Coxeter group is of classical type, or one of the exceptional types H 3 H_3 , E 6 E_6 and E 7 E_7 .

Topological quantum field theories from Hecke algebras
We construct two-dimensional non-commutative topological quantum field theories (TQFTs), one for each Hecke algebra corresponding to a finite Coxeter system. These TQFTs associate an invariant to each ciliated surface, which is a Laurent polynomial for punctured surfaces. There is a graphical way to compute the invariant using minimal colored graphs. We give explicit formulas in terms of the Schur elements of the Hecke algebra and prove positivity properties for the invariants when the Coxeter group is of classical type, or one of the exceptional types $H_3$, $E_6$ and $E_7$.Open AccessTopological quantum field theories from Hecke algebras
