Celestial Topology, Symmetry Theories, and Evidence for a NonSUSY D3‐Brane CFT

Fortschritte der Physik, Volume 73, Issue 4, April 2025.
Abstract Symmetry Theories (SymThs) provide a flexible framework for analyzing the global categorical symmetries of a D$D$‐dimensional QFTD$\text{QFT}_{D}$ in terms of a (D+1)$(D+1)$‐dimensional bulk system SymThD+1$\text{SymTh}_{D+1}$. In QFTs realized via local string backgrounds, these SymThs naturally arise from dimensional reduction of the linking

Lagrangian approximation of totally real concordances

Proceedings of the London Mathematical Society, Volume 130, Issue 4, April 2025.
Abstract We show that a two‐dimensional totally real concordance can be approximated by a Lagrangian concordance whose Legendrian boundary has been stabilised both positively and negatively sufficiently many times. The main applications that we provide are constructions of knotted Lagrangian concordances in arbitrary four‐dimensional symplectisations ...

W0_sample = np.random.normal(0,1)?

Physics Letters B
In this note, we explore the distribution of vacuum expectation values of the superpotential W0 in explicit Type IIB flux compactifications. We show that the distribution can be approximated universally across geometries by a two-dimensional Gaussian ...

Substitutions on compact alphabets

Journal of the London Mathematical Society, Volume 111, Issue 3, March 2025.
Abstract We develop a systematic approach to continuous substitutions on compact Hausdorff alphabets. Focussing on implications of irreducibility and primitivity, we highlight important features of the topological dynamics of their (generalised) subshifts.

On scale-separated supersymmetric $$\hbox {AdS}_2$$ AdS 2 flux vacua

European Physical Journal C: Particles and Fields
We argue that scale-separated $$\hbox {AdS}_2$$ AdS 2 vacua with at least two preserved supercharges cannot arise from flux compactifications in a regime of computational control.

Type IIA Flux Vacua and $\alpha'$-corrections

, 2019
We analyse type IIA Calabi-Yau orientifolds with backgroud fluxes, taking into account the effect of perturbative $\alpha'$-corrections. In particular, we consider the $\alpha'$-corrections that modify the metrics in the K\"ahler sector of the ...

Groups with exotic finiteness properties from complex Morse theory

Journal of Topology, Volume 18, Issue 1, March 2025.
Abstract Recent constructions have shown that interesting behaviours can be observed in the finiteness properties of Kähler groups and their subgroups. In this work, we push this further and exhibit, for each integer k$k$, new hyperbolic groups admitting surjective homomorphisms to Z${\mathbb {Z}}$ and to Z2${\mathbb {Z}}^{2}$, whose kernel is of type ...

Racetrack potentials and the de Sitter swampland conjectures

Journal of High Energy Physics, 2019
We show that one can find de Sitter critical points (saddle points) in models of flux compactification of Type IIB String Theory without any uplifting terms and in the presence of several moduli.
