Pauli blocking effects on pair creation in strong electric field

TL;DR

This paper investigates how Pauli blocking influences electron-positron pair creation in strong electric fields, revealing suppression effects and the importance of initial plasma conditions on pair production dynamics.

Contribution

It introduces a detailed analysis of Pauli exclusion effects on pair creation, including the impact of initial plasma distributions and temperature on the process.

Findings

Pair creation is suppressed by Pauli blocking, leading to longer oscillation times.

Initial plasma conditions, such as temperature and chemical potential, significantly affect pair production.

Heating the plasma enhances pair creation, contrary to suppression effects.

Abstract

The process of electron-positron pair creation and oscillation in uniform electric field is studied, taking into account Pauli exclusion principle. Generally, we find that pair creation is suppressed, hence coherent oscillations occur on longer time scales. Considering pair creation in already existing electron-positron plasma we find that the dynamics depends on pair distribution function. We considered Fermi-Dirac distribution of pairs and found that for small temperatures pair creation is suppressed, while for small chemical potentials it increases: heating leads to enhancement of pair creation.
