标题： Mimicking a rotating black hole with nonlinear electrodynamics

摘要： 我们展示了在非线性电动力学框架下构建的第一个旋转黑洞的类比模型。 假设背景电磁场是代数特殊的，并且适应于闵可夫斯基时空中的测地线无剪切光束族，即克尔光束族。 相应的光学度规具有克尔-席尔德形式，并且被证明由三个参数表征，从而预测了能层表面、视界以及与克尔度规中也存在的一个切片相同。 显示英文摘要

摘要： We exhibit the first analogue model of a rotating black hole constructed in the framework of nonlinear electrodynamics. The background electromagnetic field is assumed to be algebraically special and adapted to a geodesic shear-free congruence of null rays in Minkowski spacetime, the Kerr congruence. The corresponding optical metric has a Kerr-Schild form and, it is shown to be characterized by three parameters, thus predicting the existence of an ergosurface, a horizon, and a slice identical to one also present in the Kerr metric.
