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…
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…
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…
