标题： Chaotic light scattering around extremal black holes

摘要： 我们证明，在平面情况下，$N\geq 3$静态极端黑洞场中的光散射是混沌的。 这种极端物体的相对论动力学简化为经典哈密顿系统。 某些稀疏子耦合值允许应用符号动力学和经典势散射的技术。 这导致了拓扑熵的一个阶数为$\log(N-1)$的下限，从而证明了$N \geq 3$黑洞中混沌散射的出现。 显示英文摘要

摘要： We show that the scattering of light in the field of $N\geq 3$ static extremal black holes is chaotic in the planar case. The relativistic dynamics of such extremal objects reduce to that of a classical Hamiltonian system. Certain values of the dilaton coupling then allow one to apply techniques from symbolic dynamics and classical potential scattering. This results in a lower bound on the topological entropy of order $\log(N-1)$, thus proving the emergence of chaotic scattering for $N \geq 3$ black holes.
