Electrostatic pair creation and recombination in quantum plasmas

Abstract

The production of electron-positron pairs by electrostatic waves in quantum plasmas is investigated. In particular, a semiclassical governing set of equations for a self-consistent treatment of pair creation by the Schwinger mechanism in a quantum plasma is derived

Plasma dynamics at the Schwinger limit and beyond

“…Before we end the discussion of the pair-creation dynamics in the presence of plasma, let us point out that there are interesting papers of relevance in this context by Refs. [37,39]. Firstly, in Ref.…”

“…Finally, in Ref. [39], production of pairs by electrostatic waves in plasma was studied using a relativistic quantum fluid model assuming that the electric field varies slowly in comparison with the Compton frequency. While the overall pair production rate used in hydrodynamics based on the Schwinger theory (proportional to exp(−πE cr /(E))) is consistent with the DHW-formalism, the kinetic details (e.g.…”

“…Nevertheless, the more modest computational demands makes hydrodynamical studies a good complement to kinetic treatments, which is illustrated by the fact that the spatial influence also could be covered in Ref. [39].…”
