In this article, we review recent theoretical works on the Schwinger mechanism of particle
production in external electrical fields. Although the non-perturbative Schwinger mechanism …

A bstract We consider line defects with large quantum numbers in conformal field theories.
First, we consider spin impurities, both for a free scalar triplet and in the Wilson-Fisher O (3) …

This is a review of the recent progress on a holographic description of the Schwinger effect.
In 2011, Semenoff and Zarembo proposed a scenario to study the Schwinger effect in the …

Using the AdS/CFT correspondence, we construct the holographic dual of a tunneling
instanton describing Schwinger pair creation in de Sitter space. Our approach allows us to …

A bstract We analyze vacuum instability of strongly coupled gauge theories in a constant
electric field using AdS/CFT correspondence. The model is the\(\mathcal {N}= 2\) 1-flavor …

A bstract We analyze electrostatic potentials in the holographic Schwinger effect. The
potential barrier for the pair production is estimated by a static potential consisting of static …

A bstract 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 back-grounds …

A bstract We consider a generalization of the holographic Schwinger effect proposed by
Semenoff and Zarembo to the case with constant electric and magnetic fields. There are two …

A bstract We consider universal aspects of a holographic Schwinger effect in general
backgrounds with an external homogeneous electric field. The argument is based on the …

A bstract Using the AdS/CFT correspondence, we calculate the vacuum decay rate for the
Schwinger effect in confining large N c gauge theories. The instability is induced by …
