Towards a String Realization of the Dark Dimension via T-folds
Guo-En Nian, Stefan Vandoren
In this work, we explore the feasibility of realizing the Dark Dimension Scenario through T-fold compactifications on , where the base of the internal space n…
Duality and Infinite Distance Limits in Asymmetric Freely Acting Orbifolds
George Gkountoumis, Chris Hull, Guo-En Nian +1
We use freely acting asymmetric orbifolds of type IIB string theory to construct a class of theories in four dimensions with eight supercharges. Their low energy effective field th…
The geometry of hypermultiplets
Stefan Vandoren
This is a light and short review on the geometry of hypermultiplets coupled to supergravity and its appearance in string theory. As is long known, the target space of the hypermult…
On Carroll partition functions and flat space holography
Georgios Poulias, Stefan Vandoren
We continue the study of Carroll limits on partition functions of relativistic conformal theories and their thermodynamics. By introducing imaginary chemical potentials conjuga…
Massive scalar clouds and black hole spacetimes in Gauss-Bonnet gravity
Iris van Gemeren, Tanja Hinderer, Stefan Vandoren
We study static black holes in scalar-Gauss-Bonnet (sGB) gravity with a massive scalar field as an example of higher curvature gravity. The scalar mass introduces an additional sca…
