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. [...]

3. 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. [...]

4. 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. [...]

5. 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. [...]

6. Instanton induced Yukawa couplings from distant E3 and E(-1) instantons / Goodsell, Mark ; Witkowski, Lukas
We calculate non-perturbative contributions to Yukawa couplings on D3-branes at orbifold singularities due to E3 and fractional E(-1) instantons which do not intersect the visible sector branes. [...]

7. 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. [...]

9. Dark Radiation predictions from general Large Volume Scenarios / Arthur Hebecker ; Patrick Mangat ; Fabrizio Rompineve ; Lukas T. Witkowski
Recent observations constrain the amount of Dark Radiation (Δ N eff ) and may even hint towards a non-zero value of Δ N eff . [...]

10. D7-brane chaotic inflation / Hebecker, Arthur ; Kraus, Sebastian C. ; Witkowski, Lukas T.
We analyze string-theoretic large-field inflation in the regime of spontaneously-broken supergravity with conventional moduli stabilization by fluxes and non-perturbative effects. [...]
