Yoshiki Sato, Kentaroh Yoshida
TL;DR
This paper investigates the Schwinger effect in confining phases using holographic models, identifying critical electric fields and conditions under which pair production occurs or is suppressed.
Contribution
It introduces a holographic approach to analyze the Schwinger effect in confining backgrounds, revealing the critical electric field and the suppression of pair production below the confining string tension.
Findings
Critical electric field causes system instability
No Schwinger effect below confining string tension
Potential analysis for D3 and D4 brane backgrounds
Abstract
We consider the Schwinger effect in confining phase by using a holographic setup. The potential analysis is performed for the confining D3-brane and D4-brane backgrounds. We find the critical electric field above which there is no potential barrier and the system becomes unstable catastrophically. An intriguing point is that no Schwinger effect occurs when the electric field is smaller than the confining string tension.
