Schwinger Effect in a Twice Anisotropic Holographic Model
Abstract
In this work, we investigate the Schwinger effect in a twice anisotropic holographic QCD model that incorporates both spatial and magnetic anisotropies. Using the AdS/CFT correspondence, we calculate the total potential of a particle-antiparticle pair to evaluate how these anisotropies affect the holographic Schwinger effect. Our calculations reveal that the magnetic field, characterized by parameters and , consistently enhances the Schwinger effect by lowering and narrowing the potential barrier. In contrast, increasing the spatial anisotropy, parameterized by , raises and widens the barrier, thereby suppressing the process. These findings suggest the significance of treating both anisotropies concurrently for a realistic description of particle production in HIC.
