Angular momentum inheritance from the Schwinger effect in (chromo)electromagnetic fields

<jats:title>Abstract</jats:title> <jats:p>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.</jats:p>
