Pair creation, backreaction, and resummation in strong fields
read the original abstract
We revisit particle creation in strong fields, and backreaction on those fields, from an amplitudes perspective. We describe the strong field by an initial coherent state of photons which we explicitly evolve in time, thus going beyond the background field approximation, and then consider observables which quantify the effects of backreaction. We present expressions for the waveform, vacuum persistence probability, and number of produced photons at next-to-leading order, all of which are impacted by backreaction, along with the number and statistics of produced pairs. We find that converting between in-out (amplitude) and in-in (expectation value) expressions requires explicit resummation of an infinite number of disconnected loop diagrams.

In-in worldline formalism in pair creating fields
In-in observables in pair-creating QED backgrounds are re-expressed exactly as in-out matrix elements with a universal non-local insertion, yielding a first-quantized formula for the probability of producing N pairs.
