本文对Einstein-Maxwell-Gauss-Bonnet（EMGB）引力场中的全息Schwinger效应进行了势分析。静电势是由经典的弦作用附加在一个探针D3-膜坐在一个中间位置的散装anti-de Sitter（AdS）空间。结果表明，化学势μ和正的Gauss-Bonnet（GB）系数λ G B使产率增大，而负的λ G B使产率减小，并利用Dirac-Born-Infeld（DBI）作用量确定了临界电场.
We perform the potential analysis in holographic Schwinger effect in Einstein–Maxwell–Gauss–Bonnet (EMGB) gravity. The static potential is evaluated by the classical string action attaching on a probe D3-brane sitting at an intermediate position in the bulk anti-de Sitter (AdS) space. It is shown that chemical potential μ and positive Gauss–Bonnet (GB) coefficient λ G B enhance the production rate while negative λ G B reduce it. Also, we determine the critical electric field by Dirac–Born–Infeld (DBI) action.
