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…
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…
F-theory flux vacua at large complex structure
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…
Smooth String Vacua in a Gravitationally Non-perturbative Regime
Mirjam CvetiÄ, 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…
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…
