摘要

本文构造了D=4时空维度上描述具有环面视界的带电旋转黑洞的SU(N) Einstein-Skyrme模型的精确解。旋转是通过对已知的具有Skyrme毛发的静态环面黑洞进行不适当的坐标变换来增加的，而电荷是通过考虑与爱因斯坦引力相互作用的U(1)规范场来补充的。我们在大规范系综中进行热分析，明确地显示了风味数所起的作用。还讨论了稳定性问题。2025年由美国物理学会出版

Exact charged and rotating toroidal black hole in the SU(N) Einstein-Skyrme model

In this paper, we construct an exact solution of the SU(N) Einstein-Skyrme model in D=4 space-time dimensions describing a charged and rotating black hole with toroidal horizon. Rotation is added by applying an improper coordinate transformation to the known static toroidal black hole with Skyrme hair, while the electric charge is supplemented by considering a U(1) gauge field interacting with Einstein gravity. We perform the thermal analysis in the grand canonical ensemble, explicitly showing the role that the flavor number plays. Some discussions about stability are also considered.
