Query: Pair Production in Rotating Electric Fields   We explore Schwinger pair production in rotating time-dependent electric
fields using the real-time DHW formalism. We determine the time evolution of
the Wigner function as well as asymptotic particle distributions neglecting
back-reactions on the electric field. Whereas qualitative features can be
understood in terms of effective Keldysh parameters, the field rotation leaves
characteristic imprints in the momentum distribution that can be interpreted in
terms of interference and multiphoton effects. These phenomena may seed
characteristic features of QED cascades created in the antinodes of a
high-intensity standing wave laser field.
