“…Indeed, the Misner string is transparent to geodesics, and the spacetime has no closed time-like or null geodesics, provided some restrictions are imposed on the parameters of the NUT solution. Furthermore, the Kruskal extension through both horizons can be carried out if there is no time periodicity [25], and it is possible to formulate a consistent thermodynamics of Taub-NUT spacetime with Misner strings present [26][27][28][29].…”

We derive a correspondence between the Hawking radiation spectra emitted from general classes of Taub-NUT black holes with that induced by the relativistic motion of an accelerated Dirichlet boundary condition (i.e., a perfectly reflecting mirror) in (1+1)-dimensional flat spacetime. We demonstrate that the particle and energy spectra is thermal at late times and that particle production is suppressed by the NUT parameter. We also compute the radiation spectrum in the rotating, electrically charged (Kerr–Newman) Taub-NUT scenario, and the extremal case, showing, explicitly, how these parameters affect the outgoing particle and energy fluxes.

“…Thus imposing time periodicity is not necessary and no causality problem occurs. Based on this argument, thermodynamic properties of Lorentzian Taub-NUT-AdS spacetime were subsequently studied [16][17][18], with the perspective that the first law has full cohomogeneity by treating the NUT charge as an independent thermodynamic variable, a Misner charge whose conjugate variable is called the Misner potential, with these new terms included in the first law and free energy.…”

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

We derive a correspondence between the Hawking radiation spectra emitted from general classes of Taub-NUT black holes with that induced by the relativistic motion of an accelerated Dirichlet boundary condition (i.e. a perfectly reflecting mirror) in flat spacetime. For Taub-NUT spacetime with positive 2-space curvature, ε = +1, we demonstrate that the particle and energy spectra is thermal at late-times and that particle production is suppressed by the NUT parameter. We derive a new class of mirror trajectories corresponding to a timereversed Taub-NUT spacetime with vanishing 2-space curvature, ε = 0, where early-time thermality and a nonmonotonic dependence on the NUT parameter are demonstrated. We also compute the radiation spectrum in the rotating, electrically charged (Kerr-Newman) Taub-NUT scenario, and the extremal case, showing explicitly how these parameters affect the outgoing particle and energy fluxes.
