Inflation from Nilpotent Kähler Corrections
Evan McDonough, Marco Scalisi
We develop a new class of supergravity cosmological models where inflation is induced by terms in the Kähler potential which mix a nilpotent superfield with a chiral sector …
Preheating and Entropy Perturbations in Axion Monodromy Inflation
Evan McDonough, Hossein Bazrafshan Moghaddam, Robert H. Brandenberger
We study the preheating of gauge fields in a simple axion monodromy model and compute the induced entropy perturbations and their effect on the curvature fluctuations. We find that…
Fermions on the Anti-Brane: Higher Order Interactions and Spontaneously Broken Supersymmetry
Keshav Dasgupta, Maxim Emelin, Evan McDonough
It has been recently argued that inserting a probe anti-D3-brane in a flux background breaks supersymmetry spontaneously instead of explicitly, as previously thought. In this paper…
