Non-minimal Elliptic Threefolds at Infinite Distance II: Asymptotic Physics

Rafael Álvarez-García, Seung-Joo Lee, Timo Weigand

We interpret infinite-distance limits in the complex structure moduli space of F-theory compactifications to six dimensions in the light of general ideas in quantum gravity. The li…

Non-minimal Elliptic Threefolds at Infinite Distance I: Log Calabi-Yau Resolutions

Rafael Álvarez-García, Seung-Joo Lee, Timo Weigand

We study infinite-distance limits in the complex structure moduli space of elliptic Calabi-Yau threefolds. In F-theory compactifications to six dimensions, such limits include infi…

D-brane and F-theory Model Building

Fernando Marchesano, Bert Schellekens, Timo Weigand

We review recent progress in the construction of four-dimensional vacua of Type II string theory and F-theory which yield the Standard Model of particle physics (SM) or extensions…

The Asymptotic Weak Gravity Conjecture in M-theory

Cesar Fierro Cota, Alessandro Mininno, Timo Weigand +1

The tower Weak Gravity Conjecture predicts infinitely many super-extremal states along every ray in the charge lattice of a consistent quantum gravity theory. We show this far-reac…

Quantum Gravity Bounds on N=1 Effective Theories in Four Dimensions

Luca Martucci, Nicolo Risso, Timo Weigand

We propose quantum gravitational constraints on effective four-dimensional theories with N=1 supersymmetry. These Swampland constraints arise by demanding consistency of the worlds…

The Asymptotic Weak Gravity Conjecture for Open Strings

Cesar Fierro Cota, Alessandro Mininno, Timo Weigand +1

We investigate the asymptotic Tower Weak Gravity Conjecture in weak coupling limits of open string theories with minimal supersymmetry in four dimensions, focusing for definiteness…
