Complement to thermodynamics of dyonic Taub-NUT-AdS spacetime

We examine the thermodynamics of Euclidean dyonic Taub-NUT/Bolt-AdS4 black holes for a variety horizon geometries to understand how gauge field regularity conditions influence thermodynamic relations. find several distinct features that distinguish NUT-charged case from its Reissner-Nordstrom counterpart. For NUT solution, vanishes at and so is ensured. Bolt solution we norm required vanish in order satisfy both first law thermodynamics. This condition yields constraint on electric magnetic charges reduces cohomogeneity system; spherical horizons, removing Misner string singularity further cohomogeneity, observe bolt solutions with increasing charge have positive heat capacity, but upon turning make dyonic, properties uncharged one are retained, having negative capacity. also study extremal finding disappears zero temperature limit. has finite-temperature-like behaviour, potential playing role similar temperature.
