Description
The standard reheating process after inflation can be preceded by preheating, a phase where the oscillations of the inflaton field at the bottom of its potential lead to explosive production of particles via parametric resonance, potentially altering the history of the universe.
I will discuss an inflating modulus, coupled to an axion via a typical potential coupling coming from type iib string theory on Calabi-Yau orientifolds and explore the consequences of parametric resonance in the string axiverse.
