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…
K-Points and Type IIB/Heterotic Duality with NS5-Branes
Jeroen Monnee, Timo Weigand, Max Wiesner
We revisit type II limits in the vector multiplet moduli space of compactifications of Type IIB string theory on Calabi-Yau threefolds. These limits are special because they ca…
Physics and Geometry of Complex Structure Limits in Type IIB Calabi-Yau Compactifications
Jeroen Monnee, Timo Weigand, Max Wiesner
We provide a detailed geometric and physical interpretation of infinite distance limits in the complex structure moduli space of Type IIB compactifications on Calabi-Yau threefolds…
Emergent Strings in Type IIB Calabi--Yau Compactifications
Bjoern Hassfeld, Jeroen Monnee, Timo Weigand +1
We study infinite distance limits in the complex structure moduli space of Type IIB compactifications on Calabi--Yau threefolds, in light of the Emergent String Conjecture. We focu…
Asymptotics of 5d Supergravity Theories and the Emergent String Conjecture
Lukas Kaufmann, Stefano Lanza, Timo Weigand
We invoke probe brane arguments to classify the asymptotic behavior of general five-dimensional supergravity theories with eight supercharges near infinite distance boundaries of t…
The Minimal Weak Gravity Conjecture
Cesar Fierro Cota, Alessandro Mininno, Timo Weigand +1
We examine the minimal constraints imposed by the Weak Gravity Conjecture (WGC) on the particle spectrum of a quantum gravity theory. Towers of super-extremal states have previousl…
