Abstract: (AIP)
We show how to do semiclassical nonperturbative computations within the worldline approach to quantum field theory using “worldline instantons”. These worldline instantons are classical solutions to the Euclidean worldline loop equations of motion, and are closed spacetime loops parametrized by the proper‐time. Specifically, we compute the imaginary part of the one loop effective action in scalar and spinor QED using worldline instantons, for a wide class of inhomogeneous electric field backgrounds.- 11.27.+d
