Drifting Oscillations in Axion Monodromy
Raphael Flauger, Liam McAllister, Eva Silverstein +1
We study the pattern of oscillations in the primordial power spectrum in axion monodromy inflation, accounting for drifts in the oscillation period that can be important for compar…
Planckian Axions in String Theory
Thomas C. Bachlechner, Cody Long, Liam McAllister
We argue that super-Planckian diameters of axion fundamental domains can naturally arise in Calabi-Yau compactifications of string theory. In a theory with axions , the fu…
Heavy Tails in Calabi-Yau Moduli Spaces
Cody Long, Liam McAllister, Paul McGuirk
We study the statistics of the metric on Kähler moduli space in compactifications of string theory on Calabi-Yau hypersurfaces in toric varieties. We find striking hierarchies in t…
The Powers of Monodromy
Liam McAllister, Eva Silverstein, Alexander Westphal +1
Flux couplings to string theory axions yield super-Planckian field ranges along which the axion potential energy grows. At the same time, other aspects of the physics remain essent…
A New Angle on Chaotic Inflation
Thomas C. Bachlechner, Mafalda Dias, Jonathan Frazer +1
N-flation is a radiatively stable scenario for chaotic inflation in which the displacements of axions with decay constants lead to a super-…
Inflation and String Theory
Daniel Baumann, Liam McAllister
We review cosmological inflation and its realization in quantum field theory and in string theory. This material is a portion of a book, also entitled "Inflation and String Theory"…
