A field theory whose energy density is finite while classically unbounded below

Presented by Kevin Cahill (UNM)

I will describe a quantum field theory whose classical energy density can assume values that are arbitrarily negative but whose actual ground-state energy density is finite. This theory is a modern echo of the hydrogen atom which has a potential energy that is unbounded below but has a ground-state energy of - 13.6 eV.

If there is time, I'll also show how to do Monte Carlo estimates of a system whose distribution is not positive definite.
