Analog Particle Production Model for General Classes of Taub-NUT Black Holes

Abstract

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.

Quantum power distribution of relativistic acceleration radiation: classical electrodynamic analogies with perfectly reflecting moving mirrors

“…(B5) 5 Accelerated boundary correspondences exist for more than just the Schwarzschild black hole [46]. See the Reissner-Nordström [47], Taub-NUT [48] and Kerr [49] black holes. De Sitter and anti-de Sitter cosmologies [50] are also modeled by moving mirrors as well as extremal black holes [51][52][53] The denominators of both hand sides of Eq.…”

Relativistic quantum information as radiation reaction: entanglement entropy and self-force of a moving mirror analog to the CGHS black hole

“…There have been a number of studies that relate different specific black hole models (e.g. the Schwarzschild [21] case) and their analog moving mirrors, including the extremal Reissner-Nordström [22,23], extremal Kerr [24], Reissner-Nordström [25], Taub-NUT [26] and Kerr [27] black holes. In addition, de Sitter and anti-de Sitter cosmologies [28] are also modeled by moving mirror trajectories.…”
