Topological changes and response singularities in black hole thermodynamic branch structure
Di Wu
In this paper, we investigate how different diagnostics characterize the thermodynamic branch structure of black holes. In three charged AdS black hole examples, the thermodynamic…

Dimensional structure of thermodynamic topology in ultraspinning Kerr-AdS black holes
Min Tian, Ying Chen, Di Wu
In this paper, we apply the thermodynamic topology framework to ultraspinning Kerr-AdS black holes in arbitrary spacetime dimensions. By constructing the off-shell Helmholtz free e…
