The Leonard E Parker Center for Gravitation, Cosmology and Astrophysics holds frequent seminars on a broad range of ongoing cosmology and gravitation research topics. Unless otherwise noted, seminars are on Friday afternoons at 1:00 PM in KIRC 2175; there is a gathering for a brown bag lunch at 12:30.

Generalized temperature and accelerated dynamics
Morgan Lynch, UWM Graduate Student

I will present recent work involved with the computation of the temperature registered by an Unruh-DeWitt detector coupled to a Hadamard renormalizable quantum field and moving along an arbitrary accelerated trajectory in curved spacetime. Then, focusing on the temperature due to acceleration, i.e. the Unruh effect, I will present an effective Fermi theory of acceleration-induced interactions. This accelerated quantum dynamics provides a framework for computing a wide class of observables to probe the physics of high acceleration. General expressions for the emission rate, multiplicity, power, spectra, and displacement law of particles undergoing time-dependent acceleration and transitioning into a final state of arbitrary particle number will be presented.
