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…

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…

Cosmic Acceleration and Turns in the Swampland
Julian Freigang, Dieter Lust, Guo-En Nian +1
We argue that field trajectories, which lead to cosmic acceleration and feature rapid turns near the boundary of the moduli space, are in the Swampland. We obtain this result by as…
