We present the derivation of Hawking radiation by using the tunneling mechanism in a rotating and charged black hole background. We show that the 4-dimensional Kerr-Newman metric, which has a spherically nonsymmetric geometry, becomes an effectively 2-dimensional spherically symmetric metric by using the technique of the dimensional reduction near the horizon. We can thus readily apply the tunneling mechanism to the nonspherical Kerr and Kerr-Newman metric.

  1. The Hawking temperature in the context of dark energy for Kerr-Newman and Kerr-Newman-AdS backgrounds

    gr-qc 2019-06 unverdicted novelty 4.0

    Hawking temperatures for emergent gravity metrics of KN and KNAdS are calculated along θ=0, modified by dark energy from DBI k-essence fields, with metrics satisfying Einstein equations at large r.
