Consistent thermodynamics and topological classes for the four-dimensional Lorentzian charged Taub-NUT spacetimes
Di Wu
In this paper, we derive the consistent thermodynamics of the four-dimensional Lorentzian charged Reissner-Nordström-NUT (RN-NUT), Kerr-Newman-NUT (KN-NUT), and RN-NUT-AdS spacetim…
Consistent mass formulas for higher even-dimensional Reissner-Nordström-NUT-AdS spacetimes
Shuang-Qing Wu, Di Wu
In our previous work [D. Wu and S.-Q. Wu, Phys. Rev. D 108, 064034 (2023)], we have formulated consistent thermodynamic first law and Bekenstein-Smarr mass formulae for all higher…
Classifying topology of consistent thermodynamics of the four-dimensional neutral Lorentzian NUT-charged spacetimes
Di Wu
In this paper, via employing the uniformly modified form of the generalized off-shell Helmholtz free energy, we investigate the topological numbers for the four-dimensional neutral…
Topological classes of rotating black holes
Di Wu
In this paper, we investigate the topological numbers for singly rotating Kerr black holes in arbitrary dimensions and four-dimensional Kerr-Newman black hole. We show that for unc…
Revisiting mass formulas of the four-dimensional Reissner-Nordström-NUT-AdS solutions in a different metric form
Di Wu, Shuang-Qing Wu
Recently, the so-called ``consistent thermodynamics'' of the Lorentzian Reissner-Nordström (RN)-NUT-AdS spacetimes has been pursued by a lot of efforts via different means. Amo…
Hunting for extra dimensions in the shadow of Sagittarius A*
Di Wu
Recently, Vagnozzi and Visinelli's work [Phys. Rev. D 100, 024020 (2020)] reveals that M87*'s shadow establishes an upper limit of AU, where is the AdS cur…
Consistent mass formulas for the four-dimensional dyonic NUT-charged spacetimes
Di Wu, Shuang-Qing Wu
In our previous work, a novel idea that the NUT charge can be thought of as a thermodynamical multi-hair has been advocated to describe perfectly the thermodynamical character of t…
Shadowless rapidly rotating yet not ultraspinning Kerr-AdS and Kerr-Newman-AdS black holes
Di Wu, Puxun Wu, Hongwei Yu
We find that the Kerr-(Newman)-AdS black hole will be shadowless if its rotation parameter is larger than a critical value and the shadowless-ness may be related to the appeara…
Aspects of the dyonic Kerr-Sen-AdS black hole and its ultraspinning version
Di Wu, Shuang-Qing Wu, Puxun Wu +1
We explore some (especially, thermodynamical) properties of the dyonic Kerr-Sen-AdS black hole and its ultraspinning counterpart, and check whether or not both black holes sati…
Are ultra-spinning Kerr-Sen-AdS black holes always super-entropic ?
Di Wu, Puxun Wu, Hongwei Yu +1
We study thermodynamics of the four-dimensional Kerr-Sen-AdS black hole and its ultra-spinning counterpart, and verify that both black holes fullfil the first law and Bekenstein-Sm…
Notes on thermodynamics of super-entropic AdS black holes
Di Wu, Puxun Wu, Hongwei Yu +1
The super-entropic black hole, which possesses a noncompact horizon topology and violates the reverse isoperimetric inequality, has been found to satisfy both the thermodynamic fir…
Hawking radiation from rotating AdS black holes in conformal gravity
Shuang-Qing Wu, Gao-Ming Deng, Di Wu
We extend to study Hawking radiation via tunneling in conformal gravity. We adopt Parikh-Wilczek's semi-classical tunneling method and the method of complex-path integral to invest…
