A Theory of Self-Resonance After Inflation, Part 1: Adiabatic and Isocurvature Goldstone Modes

Understand

We develop a theory of self-resonance after inflation.

• We study a large class of models involving multiple scalar fields with an internal symmetry.
• For illustration, we often specialize to dimension 4 potentials, but we derive results for general potentials.
• This is the first part of a two part series of papers.
