Thesis Defense
Asymptotic series and gravitational particle production
Date: Tuesday, November 29th
Time: 2:00 pm
Place: 4274 Chamberlin
Speaker: Edward Basso, Physics Graduate Student
Abstract: The dynamics of the coherent oscillation period of inflation are solved using a formalism of asymptotic expansions reminiscent of renormalization in gauge theory. This yields an analytic description of the fluctuations observed in the spectral density of gravitationally produced particles. These spectral fluctuations can be interpreted as quantum interference between gravitational scattering amplitudes due to the coherent oscillatory state of the inflaton field.
