Angular Momentum Inheritance from the Schwinger Effect in (Chromo)electromagnetic Fields

Abstract

The angular momentum of fermion pairs generated by the Schwinger effect is studied in homogeneous (chromo)electromagnetic fields, mimicking the early stages of a heavy-ion collision. It is demonstrated that the angular momentum density of produced pairs is proportional to that of the background fields. This is argued both heuristically in a virtual breaking condensate model by evaluating Wong's equations, and out-of-equilibrium to one-loop using the in-in formalism.
