Quantum Gravity Principles for 4d Supergravity Theories and Asymptotic Hodge Theory
Lukas Kaufmann, Timo Weigand
We study the behaviour of general four-dimensional N=2 supergravity theories near boundaries at infinity of the vector multiplet moduli space, with a focus on a clear distinction b…
Testing F-theory GUTs with the Axiverse
Michael Nee, Mario Reig, Timo Weigand
We show that axions coupled to photons in F-theory Grand Unified Theories (GUTs) satisfy the coupling-to-mass relation ,…
On Quantum Obstructions in Type IIA Orientifolds
Lukas Kaufmann, Timo Weigand, Max Wiesner
Quantum corrections can severely modify or even remove classical infinite distance limits in four-dimensional gravity theories with minimal N=1 supersymmetry. In this note we study…
Quantum obstructions for infinite distance limits -- Part I: obstructions
Lukas Kaufmann, Jeroen Monnee, Timo Weigand +1
We analyse quantum obstructions to classical infinite distance limits in four-dimensional string compactifications with N=1 supersymmetry. Such quantum effects signal a severe depa…
Quantum obstructions for infinite distance limits -- Part II: Kähler obstructions
Lukas Kaufmann, Jeroen Monnee, Timo Weigand +1
We continue our analysis of quantum corrections in the complex structure moduli space of four-dimensional Type IIB/F-theory compactifications with N=1 supersymmetry. We find that l…
Multiplet Recombination and the CFT Distance Conjecture
Fabio Mantegazza, Enrico Marchetto, Elli Pomoni +2
Motivated by quantum gravity and the CFT Distance Conjecture, we study infinite-distance limits in four-dimensional superconformal field theories with higher-dimension…
Bounds on the Mordell-Weil rank of elliptic fibrations
Antonella Grassi, Rick Miranda, Kapil Paranjape +2
We prove that the Mordell-Weil group of a higher dimensional elliptic fibration naturally embeds into that of a suitable elliptic surface. We give sufficient conditions for the exi…
