Breakdown of the vacuum by arbitrary external fields

We examine the spontaneous breakdown of the matter vacuum triggered by an external force. Based on the multi-particle counting numbers, which are accessible by experiment, we present a general theoretical procedure that permits the computation of the vacuum probability for sub- and super-critical fields with arbitrary spatial and temporal profiles. When the field is supercritical, the theory leads to the expected exponentially decay of the vacuum in the long-time limit. For the special case of an infinitely extended electric force field, we establish the validity of an effective decay constant obtained by averaging the Schwinger rate over the spatial force profile.
