论文摘要
麦克斯韦的方程在二元旋转和形式转换下都是不变的。最近,Bandos,Lechner,Sorokin和Townsend发现了具有这两种对称性的电动力学的非线性概括。我们将该理论融为一体,并以明确的物理解释探索自我磨损的配置。我们发现带电的黑洞和精确的重力波。黑洞的几何形状是Reissner-Nordström,但是,非线性参数是筛选因子,允许在黑洞质量小于电荷的极端构型中。此外,我们还讨论了双折射的现象,并确定与光子传播相关的光学指标。
Maxwell's equations are invariant under both duality rotations and conformal transformations. Recently Bandos, Lechner, Sorokin, and Townsend have found a nonlinear generalisation of electrodynamics which possesses both of these symmetries. We couple this theory to General Relativity and explore self-gravitating configurations with a clear physical interpretation. We find charged black holes and exact gravitational waves. The black hole geometry is Reissner-Nordström, however, the non-linearity parameter acts as a screening factor allowing extremal configurations where the mass of the black hole is smaller than its charge. Furthermore, we also discuss the phenomenon of birefringence and determine the optical metrics associated to the propagation of photons.
