1. Flat monodromies and a Moduli Space Size Conjecture / Hebecker, Arthur ; Henkenjohann, Philipp ; Witkowski, Lukas
We investigate how super-Planckian axions can arise when type IIB 3-form flux is used to restrict a two-axion field space to a one-dimensional winding trajectory. [...]

2. The Weak Gravity Conjecture and the axionic black hole paradox / Hebecker, Arthur ; Soler, Pablo
In theories with a perturbatively massless 2-form (dual to an axion), a paradox may arise in the process of black hole evaporation. [...]

4. Can gravitational instantons really constrain axion inflation? / Hebecker, Arthur ; Mangat, Patrick ; Theisen, Stefan ; Witkowski, Lukas
Axions play a central role in inflationary model building and other cosmological applications. [...]

5. Gravitational waves from axion monodromy / Hebecker, Arthur ; Jaeckel, Joerg ; Rompineve, Fabrizio ; Witkowski, Lukas T.
Large field inflation is arguably the simplest and most natural variant of slow-roll inflation. [...]

6. Axion monodromy and the weak gravity conjecture / Hebecker, Arthur ; Rompineve, Fabrizio ; Westphal, Alexander
Axions with broken discrete shift symmetry (axion monodromy) have recently played a central role both in the discussion of inflation and the ‘relaxion’ approach to the hierarchy problem. [...]

7. Axion monodromy inflation with warped KK-modes / Hebecker, Arthur ; Moritz, Jakob ; Westphal, Alexander ; Witkowski, Lukas T.
We present a particularly simple model of axion monodromy inflation: Our axion is the lowest-lying KK-mode of the RR-2-form-potential C2 in the standard Klebanov–Strassler throat. [...]

8. Winding out of the Swamp: Evading the weak gravity conjecture with F -term winding inflation? / Hebecker, Arthur ; Mangat, Patrick ; Rompineve, Fabrizio ; Witkowski, Lukas T.
We present a new model of large field inflation along a winding trajectory in the field space of two axionic fields, where the “axions” originate from the complex structure moduli sector of a Calabi–Yau 3-fold at large complex structure. [...]
