Two-Horizon Sector Thermodynamics as a Diagnostic for the Bi-Hair Organization of NUT Charge
Di Wu, Robert B. Mann, Shuang-Qing Wu
After decades without a fully self-consistent thermodynamic formulation, recent proposals for Lorentzian Taub-NUT spacetime have yielded several inequivalent descriptions, each sat…
Thermodynamics and topological classifications of static non-extremal four-charge AdS black hole in the five-dimensional , gauged supergravity
Di Wu, Shuang-Qing Wu
In this paper, we investigate thermodynamical aspects of a novel static non-extremal black hole solution in the five-dimensional anti-de Sitter (AdS) space carrying four independen…
Four-charge static non-extremal black holes in the five-dimensional , supergravity
Di Wu, Shuang-Qing Wu
We construct, for the first time, new static non-extremal five-dimensional black hole solutions (without or with squashed horizons) endowing with four different electric charge par…
Novel topological classes in black hole thermodynamics
Di Wu, Wentao Liu, Shuang-Qing Wu +1
By viewing black hole solutions as topological defects in thermodynamic parameter space, we unveil a novel topological class and two new topological subclasses, respectively denote…
Is the type-D NUT C-metric really "missing" from the most general Plebański-Demiański solution?
Shuang-Qing Wu, Di Wu
It remains a long-standing problem, unsettled for almost two decades in the general relativity community, ever since Griffiths and Podolsky demonstrated in Ref. [J.B. Griffiths and…
