• Constraints on axion inflation from the weak gravity conjecture (2015, background): “To get a realistic model of nature with chiral matter and N = 1 supersymmetry, one would have to insert orientifold planes under whose orientifold action the cohomology group H1,1 splits into a parity-even and parity-odd part [28], H(1,1)(Z) = H(1,1) + (Z)⊕H 1,1 − (Z).”
• Relaxion monodromy and the Weak Gravity Conjecture (2015, background): “This possibly endangers the stability of the potential against higher dimensional operators, a familiar issue in large field inflation models (see [12] for a review).”
