Title: Bounces and prefactors for false vacuum decay

A precise determination of probability to nucleate a bubble of false vacuum is a fascinating
and complex task. We will discuss a recent polygonal approach for evaluating the rate for arbitrary
multi-field potentials and the resulting FindBounce package. Then we turn to the functional determinant, 
which sets the prefactor of the rate. We find a fully analytic result in the thin wall limit and thereby complete
the challenge left unfinished by Coleman and Callan in their seminal work.
