Instantons and infinite distances
Fernando Marchesano, Max Wiesner
We consider geodesics of infinite length and constant 4d dilaton in the (classical) hypermultiplet moduli space of type II Calabi-Yau compactifications. When approaching such infin…
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…
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…
Non-perturbative Resolution of Strong Coupling Singularities in 4d N=1 Heterotic/M-theory
Mirjam CvetiÄ, Max Wiesner
We investigate the interior of the moduli space of four-dimensional theories of gravity arising from compactifications of the heterotic string on Ca…
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 …
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…
