What makes spacetime spin in string theory?
Matilda Delgado, Lorenz Eberhardt, Marija TomaÅ¡eviÄ
Type II string theory in the absence of orientifolds requires the target spacetime to admit a spin structure. We show that this familiar requirement arises directly from the co…
A Duality Web for Non-Supersymmetric Strings
Zihni Kaan Baykara, Matilda Delgado, Emilian Dudas +2
Motivated by the recently proposed geometric descriptions of 0A and 0B in M-theory and F-theory, we propose a web of duality among non-supersymmetric strings. In particular we argu…
Finiteness and the Emergence of Dualities
Matilda Delgado, Damian van de Heisteeg, Sanjay Raman +3
We argue that the finiteness of quantum gravity amplitudes in fully compactified theories (at least in supersymmetric cases) leads to a bottom-up prediction for the existence of no…
Black Holes, Moduli Stabilisation and the Swampland
Matilda Delgado, Sébastien Reymond, Thomas Van Riet
In theories with moduli, extremal black holes behave such that for generic initial conditions, the distance traveled by the scalars from infinity to the horizon can grow with the s…
Classical Black Hole Probes of UV Scales
José Calderón-Infante, Matilda Delgado, Yixuan Li +2
In the context of the Swampland program, black hole attractors have been employed to probe infinite distances in moduli space, where the EFT cutoff goes to zero in Planck units and…
To curve, or not to curve: Is curvature-assisted quintessence observationally viable?
George Alestas, Matilda Delgado, Ignacio Ruiz +3
Single-field models of accelerated expansion with nearly flat potentials, despite being able to provide observationally viable explanations for the early-time cosmic inflation and…
