Special Points of Inflation in Flux Compactifications
Iñaki García-Etxebarria, Thomas W. Grimm, Irene Valenzuela
We study the realisation of axion inflation models in the complex structure moduli spaces of Calabi-Yau threefolds and fourfolds. The axions arise close to special points of these…
The effective action of warped M-theory reductions with higher derivative terms - Part I
Thomas W. Grimm, Tom G. Pugh, Matthias Weissenbacher
M-theory accessed via eleven-dimensional supergravity admits globally consistent warped solutions with eight-dimensional compact spaces if background fluxes and higher derivative t…
Complete Intersection Fibers in F-Theory
Volker Braun, Thomas W. Grimm, Jan Keitel
Global F-theory compactifications whose fibers are realized as complete intersections form a richer set of models than just hypersurfaces. The detailed study of the physics associa…
Yukawas and discrete symmetries in F-theory compactifications without section
Iñaki García-Etxebarria, Thomas W. Grimm, Jan Keitel
In the case of F-theory compactifications on genus-one fibrations without section there are naturally appearing discrete symmetries, which we argue to be associated to geometricall…
Partial Supergravity Breaking and the Effective Action of Consistent Truncations
Thomas W. Grimm, Andreas Kapfer, Severin Lust
We study vacua of N = 4 half-maximal gauged supergravity in five dimensions and determine crucial properties of the effective theory around the vacuum. The main focus is on configu…
On M-theory fourfold vacua with higher curvature terms
Thomas W. Grimm, Tom G. Pugh, Matthias Weissenbacher
We study solutions to the eleven-dimensional supergravity action, including terms quartic and cubic in the Riemann curvature, that admit an eight-dimensional compact space. The int…
Physics of F-theory compactifications without section
Lara B. Anderson, Iñaki García-Etxebarria, Thomas W. Grimm +1
We study the physics of F-theory compactifications on genus-one fibrations without section by using an M-theory dual description. The five-dimensional action obtained by considerin…
Axion Inflation in F-theory
Thomas W. Grimm
We study the dynamics of axion-like fields in F-theory and suggest that they can serve as inflatons in models of natural inflation. The axions arise from harmonic three-forms on th…
Self-Dual Tensors and Partial Supersymmetry Breaking in Five Dimensions
Thomas W. Grimm, Andreas Kapfer
We study spontaneous supersymmetry breaking of five-dimensional supergravity theories from sixteen to eight supercharges in Minkowski vacua. This N=4 to N=2 breaking is induced by…
