Schwinger pairs production in a soft-wall model

Abstract

The Schwinger pairs production rate is calculated numerically in the soft-wall model with the help of a simpler method in determining the soft-wall's position beyond which probe strings connecting the Schwinger pairs do not fall into. The critical behaviour of the production rate and linear part in the middle region are both studied carefully. The latter manifests interesting new features. The results are compared with those in previous hard-wall models.

Holographic Schwinger effect in the dynamical AdS/QCD model

“…It was found that the potential barrier will vanish and the Schwinger effect occurs when the external electric field E is equal or greater than the critical field E c . The production rate of pairs has been discussed in [13][14][15][16][17]. [18] has studied the production of the pairs in the non-supersymmetric QCD background.…”
