Hawking radiation of scalar particles from accelerating and rotating black holes

Abstract

Hawking radiation of uncharged and charged scalars from accelerating and rotating black holes is studied. We calculate the tunneling probabilities of these particles from the rotation and acceleration horizons of these black holes. Using the tunneling method we recover the correct Hawking temperature as well.-1 -

Quantum tunneling from three-dimensional black holes

“…For this charged black hole, there is a limit l → ∞, Λ → 0, in which it goes over to charged black hole asymptotic to flat space. The electrically charged and rotating black holes take the form (2.2), but with 10) where Q is the electric charge, and J is the angular momentum of the black hole. Using the fact that for BTZ black hole electric potential, A µ , is given by (A t , 0, 0) , we have from (2.6) and (2.9)…”

“…These radiations have also been viewed as quantum tunneling of particles from the horizons of black holes [3,4,5]. Many well known black holes have been researched for these radiations [6][7][8][9][10][11][12]. In one of the procedures the wave equation governing the emission of particles is solved in the background of the black hole spacetimes by using complex path integration techniques and WKB approximation.…”

Fermions tunneling from Plebański-Demiański black holes

“…(20), the Hawking temperature of the accelerating and rotating BHs, electric and magnetic charges is recovered [8]. For α = 0, it reduces to the temperature of non-accelerating BHs [9], while l = 0, k = 1, α = 0, gives Hawking temperature of the Kerr-Newman BH [5], which further reduces to the temperature of the RN BH (for a = 0).…”

“…Chen et al [7] investigated Hawking radiation spectrum via spin-1/2 particles tunneling from rotating BHs in de Sitter space and recovered their corresponding Hawking temperatures. Recently, the tunneling probabilities from accelerating and rotating BHs have been investigated for different particles [8]. Also, the thermodynamical properties of accelerating and rotating BHs with Newman-Unti-Tamburino (NUT) parameter have been studied [9].…”

Uncharged Massless Particle Tunneling from Kerr-Newman-NUT Blackhole

“…Following this tunneling method , there have been many generalizations , such as its application to other spacetimes. The Hawking radiation as tunneling from various spherically symmetric blackholes were found in [10,11,12,13,14,15,16,17,18,19,20,21,22,23]. Also , there are some attempts to extend this method to the case of stationary axisymmetric blackholes [24,25,26,27,28,29,30,31,32].…”
