General inflaton potentials in supergravity

Renata Kallosh, Andrei Linde, Tomas Rube

We describe a way to construct supergravity models with an arbitrary inflaton potential V (ϕ) and show that all other scalar fields in this class of models can be stabilized at the…

Supercurvaton

Vittoria Demozzi, Andrei Linde, Viatcheslav Mukhanov

We discuss observational consequences of the curvaton scenario, which naturally appears in the context of the simplest model of chaotic inflation in supergravity. The non-gaussiani…

Non-perturbative String Theory from Water Waves

Ramakrishnan Iyer, Clifford V. Johnson, Jeffrey S. Pennington

We use a combination of a 't Hooft limit and numerical methods to find non-perturbative solutions of exactly solvable string theories, showing that perturbative solutions in differ…

Massive Degeneracy and Goldstone Bosons: A Challenge for the Light Cone

Marvin Weinstein

Wherein it is argued that the light front formalism has problems dealing with Goldstone symmetries. It is further argued that the notion that in hadron condensates can explain Gold…

Topics in Cubic Special Geometry

Stefano Bellucci, Alessio Marrani, Raju Roychowdhury

We reconsider the sub-leading quantum perturbative corrections to N=2 cubic special Kaehler geometries. Imposing the invariance under axion-shifts, all such corrections (but the im…

Simple exercises to flatten your potential

Xi Dong, Bart Horn, Eva Silverstein +1

We show how backreaction of the inflaton potential energy on heavy scalar fields can flatten the inflationary potential, as the heavy fields adjust to their most energetically favo…
