Holographic Schwinger effect in a rotating strongly coupled medium

TL;DR

This paper investigates how rotation in a strongly coupled medium influences the holographic Schwinger effect, showing that increased angular velocity lowers the potential barrier and critical electric field, thus facilitating quark-antiquark pair production.

Contribution

It provides a detailed potential analysis of the holographic Schwinger effect in a rotating deformed AdS black-hole background, revealing the impact of angular velocity on pair production.

Findings

Angular velocity decreases the potential barrier for pair production.

Higher angular velocity lowers the critical electric field needed.

Rotation makes quark-antiquark pair production easier.

Abstract

We perform the potential analysis for the holographic Schwinger effect in a rotating deformed AdS black-hole background. We calculate the total potential of a quark-antiquark ($Q\bar{Q}$) pair in an external electric field and evaluate the critical electric field from Dirac-Born-Infeld (DBI) action. It is shown that the inclusion of angular velocity decreases the potential barrier thus enhancing the Schwinger effect, opposite to the effect of the confining scale. Moreover, by increasing angular velocity decreases the critical electric field above which the pairs are produced freely without any suppression. Furthermore, we conclude that producing $Q\bar{Q}$ pairs would be easier in rotating medium.
