Abstract

According to gauge/gravity correspondence, we study the holographic Schwinger effect within an anisotropic background. Firstly, the separate length of the particle–antiparticle pairs is computed within the context of an anisotropic background which is parameterized by dynamical exponent $ν$ $\nu$ . It is found that the maximum separate length x increases with the increase of dynamical exponent $ν$ $\nu$ . By analyzing the potential energy, we find that the potential barrier increases with the dynamical exponent $ν$ $\nu$ at a small separate distance. This observation implies that the Schwinger effect within an anisotropic background is comparatively weaker when contrasted with its manifestation in an isotropic background. Finally, we also find that the Schwinger effect in the transverse direction is weakened compared to the parallel direction in the anisotropic background, which is consistent with the top-down model.
