Quantum Corrections for a Bardeen Regular Black Hole
In this paper, we study the quantum corrections to the thermodynamical
quantities (temperature and entropy) for a Bardeen charged regular black hole
by using a quantum tunneling approach over semiclassical approximations. Taking
into account the quantum effects, the semiclassical Bekenstein-Hawking
temperature and the area law are obtained, which are then used in the first law
of thermodynamics to evaluate corrections to these quantities. It is
interesting to mention here that these corrections reduce to the corresponding
corrections for the Schwarzschild black hole when the charge .Comment: 14 pages, accepted for publication in J. Korean Phys. So
Fermions Tunneling from Charged Accelerating and Rotating Black Holes with NUT Parameter
This paper is devoted to the study of Hawking radiation as a tunneling of
charged fermions through event horizons of a pair of charged accelerating and
rotating black holes with NUT parameter. We evaluate tunneling probabilities of
outgoing charged particles by using the semiclassical WKB approximation to the
general covariant Dirac equation. The Hawking temperature corresponding to this
pair of black holes is also investigated. For the zero NUT parameter, we find
results consistent with those already available in the literature.Comment: 21 pages, no figur
Charged Vector Particles Tunneling From A Pair of Accelerating and Rotating and Gauged Super-Gravity Black Holes
The aim of this paper is to study the quantum tunneling process for charged
vector particles through the horizons of black holes by using Proca equation.
For this purpose, we have consider a pair of charged accelerating and rotating
black holes with NUT parameter and a black hole in gauged supergravity,
respectively. Further, we have studied the tunneling probability and
corresponding Hawking temperature for both black holes by using WKB
approximation.Comment: 17 Pages. Title modified and minor corrections. Submitted for
