A Theory of Self-Resonance After Inflation, Part 2: Quantum Mechanics and Particle-Antiparticle Asymmetry

Understand

We further develop a theory of self-resonance after inflation in a large class of models involving multiple scalar fields.

• We concentrate on inflaton potentials that carry an internal symmetry, but also analyze weak breaking of this symmetry.
• This is the second part of a two part series of papers.
• Here in Part 2 we develop an understanding of the resonance structure from the underlying many particle quantum mechanics.
