Topological classes of rotating black holes

D Wu - Physical Review D, 2023‏ - APS
In this paper, we investigate the topological numbers for the singly rotating Kerr black holes
in all dimensions and the four-dimensional Kerr-Newman black hole. We show that for …

A note on complex spacetime metrics

E Witten - Frank Wilczek: 50 years of theoretical physics, 2022‏ - World Scientific
For various reasons, it seems necessary to include complex saddle points in the “Euclidean”
path integral of General Relativity. But some sort of restriction on the allowed complex …

[HTML][HTML] Topological classes of thermodynamics of the rotating charged AdS black holes in gauged supergravities

XD Zhu, D Wu, D Wen - Physics Letters B, 2024‏ - Elsevier
