Connecting flux vacua through scalar field excursions
Gary Shiu, Flavio Tonioni, Vincent Van Hemelryck +1
We show how flux vacua that differ from each other in flux quanta can be seen as different vacua in a single scalar potential of an enlarged field space, which resolves the separat…
No accelerating scaling cosmologies at string tree level?
Thomas Van Riet
We investigate the scalar potential of string compactifications in the parametric regime where string loops and higher derivative corrections to 10d supergravity can be ignored and…
Axion-de Sitter wormholes
Sergio E. Aguilar-Gutierrez, Thomas Hertog, Rob Tielemans +2
We construct wormholes supported by axion flux in the presence of a positive cosmological constant. The solutions describe compact, one-handle bodies colloquially known as kettlebe…
Beginners lectures on flux compactifications and related Swampland topics
Thomas Van Riet, Gianluca Zoccarato
These lecture notes provide a pedagogical introduction, with exercises, to the techniques used in attempts to construct vacua with stabilised moduli in string theory. The reader is…
Trustworthy de Sitter compactifications of string theory: a comprehensive review
Iosif Bena, Mariana Graña, Thomas Van Riet
We attempt to review all trustworthy and well-controlled de Sitter compactifications of string theory.
A 10d construction of Euclidean axion wormholes in flat and AdS space
Gregory J. Loges, Gary Shiu, Thomas Van Riet
Euclidean wormhole geometries sourced by axions and dilatons are puzzling objects in quantum gravity. From one side of the wormhole to the other, the scalar fields traverse a few P…
