Hawking Radiation via Tunneling From Kerr Black Holes

Abstract

In this paper, Parikh's recent work, which treats Hawking radiation as a tunneling process in a spherically symmetric spacetime, is extended to the stationary axisymmetric Kerr spacetime. A generalized Painleve coordinate system (Painleve–Kerr coordinates) is introduced. The new coordinates are well-behaved at the event horizon. Constant-time slices are just flat Euclidean space in radial and satisfy Landau's condition of clock synchronization. The tunneling process across the Kerr black hole event horizon is investigated and the correctd radiation spectrum is obtained. The result is consistent with an underlying unitary theory.

Charged particles' tunnelling from the Kerr–Newman black hole

“…In fact, the first problem is solved in Ref. [13]. In similar manner we can obtain the concrete expression of the equation of motion.…”

Quantum tunneling makes a Reissner–Nordstrom black hole turn into a Kerr–Newman black hole under angular momentum conservation

“…Because of the complexity of the stationary axisymmetric Kerr and Kerr-Newman black holes (Kerr 1963), the tunneling effect must be investigated in the dragging coordinate system. Jingyi Zhang and Zheng Zhao have extended this method from spherical state case to the general axisymmetric Kerr and Kerr-Newman black holes, and even have studied more general massive and charged tunneling (Zhang and Zhao 2005a, 2005b, 2005c, 2005d. The results are all successful.…”

Massive Particles' Hawking Radiation via Tunneling From the G.H. Dilaton Black Hole

“…But in this paper we consider the tunneling of massive particles. When the massive particles tunnel across the horizon, they do not follow the radial lightlike geodesics in (7). In order to obtain the · r of massive particles, and for the sake of simplicity, we consider the outgoing massive particle as a massive shell (nonrelativistic de Broglie s-wave).…”
