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…

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…
Smooth String Vacua in a Gravitationally Non-perturbative Regime
Mirjam Cvetič, Max Wiesner
The strong coupling regime of four-dimensional N=2 supersymmetric vacua of the heterotic string is analyzed from a dual domain wall perspective. Using modular invariance, we comput…
Towards the Non-Perturbative Completion of 4d N=1 Effective Theories of Gravity
Gonzalo F. Casas, Max Wiesner
We show that four-dimensional effective theories of gravity obtained from string compactifications require a non-perturbative completion, as additional light states…

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…

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…

We analyse divergences of the scalar curvature of the vector multiplet moduli space of type IIA string theory compactified on a Calabi--Yau , along infinite-distance large v…

We investigate the interior of the moduli space of four-dimensional theories of gravity arising from compactifications of the heterotic string on Ca…

Alek Bedroya, Rashmish K. Mishra, Max Wiesner
We study universal features of the density of one-particle states in weakly coupled theories of gravity at energies above the quantum gravity cutoff , defined as the scal…
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…
Species Scale in Diverse Dimensions
Damian van de Heisteeg, Cumrun Vafa, Max Wiesner +1
In a quantum theory of gravity, the species scale can be defined as the scale at which corrections to the Einstein action become important or alternatively as codifying the "…
Bounds on Field Range for Slowly Varying Positive Potentials
Damian van de Heisteeg, Cumrun Vafa, Max Wiesner +1
In the context of quantum gravitational systems, we place bounds on regions in field space with slowly varying positive potentials. Using the fact that , where is…
Bounds on Species Scale and the Distance Conjecture
Damian van de Heisteeg, Cumrun Vafa, Max Wiesner
The species scale serves as a UV cutoff in the gravitational sector of an EFT and can depend on the moduli of the theory as the spectrum of the theory varies. We a…
Moduli-dependent Species Scale
Damian van de Heisteeg, Cumrun Vafa, Max Wiesner +1
The counting of the number of light modes in a gravitational theory is captured by the notion of the `species scale', which serves as an effective UV cutoff below the Planck scale.…
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…

We consider 4d N=1 theories arising from F-theory compactifications on elliptically-fibered Calabi-Yau four-folds and investigate the non-perturbative structure of their scalar fie…
The Tadpole Conjecture in the Interior of Moduli Space
Severin Lüst, Max Wiesner
We revisit moduli stabilization on Calabi-Yau manifolds with a discrete symmetry. Invariant fluxes allow for a truncation to a symmetric locus in complex structure moduli space and…

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…
Holography and the KKLT Scenario
Severin Lüst, Cumrun Vafa, Max Wiesner +1
The KKLT scenario, one of the few ideas to realize dS vacua in string theory, consists of two steps: the first involves the construction of a supersymmetric AdS vacuum with a small…

Fernando Marchesano, Max Wiesner
Weakly coupled regions of 4d EFTs coupled to gravity are particularly suitable to describe the backreaction of BPS fundamental axionic strings, dubbed EFT strings, in a local patch…

Fernando Marchesano, David Prieto, Max Wiesner
We compute the flux-induced F-term potential in 4d F-theory compactifications at large complex structure. In this regime, each complex structure field splits as an axionic field pl…
