Di Wu

AI总结:

本研究利用广义离壳亥姆霍兹自由能的一致修正形式,对三类四维中性洛伦兹NUT荷时空的热力学拓扑数开展研究,发现其可归入已知黑洞解类别,佐证了这类时空的普通黑洞属性。

摘要:

本文采用广义离壳亥姆霍兹自由能的一致修正形式,研究了四维中性洛伦兹Taub-NUT、Taub-NUT-AdS和Kerr-NUT时空的拓扑数,发现这些解也可归入三类已知黑洞解中的一类,表明从热力学拓扑方法的视角来看,这类时空应被视为普通黑洞。

英文摘要:

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 Lorentzian Taub-NUT, Taub-NUT-AdS and Kerr-NUT spacetimes, and find that these solutions can also be classified into one of three types of those well-known black hole solutions, which implies that these spacetimes should be viewed as generic black holes from the viewpoint of the thermodynamic topological approach.
