Abstract

Abstract We perform the potential analysis for the holographic Schwingereffect in spinning Myers-Perry black holes. We compute thepotential between the produced pair by evaluating the classicalaction of a string attaching on a probe D3-brane sitting at anintermediate position in the AdS bulk. It turns out thatincreasing the angular momentum reduces the potential barrier thusenhancing the Schwinger effect, consistent with previous findingsobtained from the local Lorentz transformation. In particular,these effects are more visible for the particle pair lying in thetransversal plane compared with that along the longitudinalorientation. In addition, we discuss how the Schwinger effectchanges with the shear viscosity to entropy density ratio atstrong coupling under the influence of angular momentum.

旋转黑洞背景中的全息Schwinger效应

摘要:我们对旋转的Myers-Perry黑洞中的全息施温格效应进行了势分析。我们通过评估连接在位于AdS体中间位置的探针d3膜上的弦的经典作用来计算产生对之间的电势。结果表明，角动量的增加降低了势垒，从而增强了施温格效应，这与先前从局部洛伦兹变换中得到的发现一致。特别是，与沿纵向方向的粒子对相比，位于横平面上的粒子对这些效应更加明显。此外，我们还讨论了在角动量的影响下，在强耦合下Schwinger效应随剪切粘度与熵密度比的变化。
