Holographic Schwinger effect in confining phase

Understand

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.
