Aros, Rodrigo2024-04-292024-04-292017-07Physical Review D Volume 96, Issue 215 July 2017 Article number 0240222470-0010https://repositorio.unab.cl/handle/ria/56439Indexación: ScopusIn this article the study of four-dimensional spaces with NUT charges and their ground states is continued. In particular, through the introduction of an improved action principle containing topological densities, it is shown that these spaces have simple and sound thermodynamical relations. As an example, the entropy of the Taub-bolt-AdS solution is computed in terms of a Noether charge. © 2017 American Physical Society.enArtículoCC BY 4.0 DEED Atribución 4.0 Internacional10.1103/PhysRevD.96.024022
