Recent research shows that Hawking radiation from black hole horizoncan be treated as a quantum tunneling process, and fermions tunneling method can successfully recover Hawking temperature. In this tunneling framework, choosing a set of appropriate matrices γμ is an important technique for fermions tunneling method. In this paper, motivated by Kerner and Man's fermions tunneling method of 4 dimension black holes, we further improve the analysis to investigate Hawking tunneling radiation from a rotating charged black hole in 5-dimensional gauged supergravity byconstructing a set of appropriate matrices γμ for general covariant Dirac equation. Finally, the expected Hawking temperature of the black hole is correctly recovered, which takes the same form as that obtained by other methods. This method is universal, and can also be directly extend to the other different-type 5-dimensional charged black holes. 相似文献

Using Damour-Ruflini's method, Hawking radiation from a general stationary black hole is investigated again deeply. Considering the back reaction of the particle to the space-time and energy conservation, we find that the radiation is not exactly thermal and can take out information from the black hole. This can be used to explain the information loss paradox, and the result is consistent with the works finished before. 相似文献

This paper investigated the massive particle radiation from Gibbons-Maeda black hole by using a semi-classical method.The calculations showed that,if the self-gravitation of the radiated particle is taken into account,the radiation spectrum deviates from exact black body spectrum and the rate of tunneling equals precisely the exponent of the difference of the black hole entropies before and after emission.The conclusion supports the viewpoint of information conservation. 相似文献

Considering the back-reaction of emitting particles to the black hole, a “new” horizon is suggested where thermodynamics can
be built in the dynamical black hole. It, at least, means that the thermodynamics of a dynamical black hole should not be
constructed at the original event horizon any more. The temperature, “new” horizon position and radiating particles’ energy
will be consistent again under the theory of equilibrium thermodynamical system.

A simple statistical interpretation of the origin of black hole entropy is presented. It is shown that this entropy can be understood as emerging as a result of missing information about the exact state of the matter from which the black hole was formed. 相似文献

Non-equilibrium Landauer transport model for Hawking radiation from a Reissner—Nordstrom black hole 下载免费PDF全文
The recent work of Nation et al., in which the Hawking radiation energy and entropy flow from a black hole is considered to be produced in a one-dimensional Landauer transport process, is extended to the case of a Reissner- Nordstrom black hole. The energy flow contains not only the contribution of the thermal flux but also that of the particle flux. It is found that the charge can also be transported via the one-dimensional quantum tunnel. Because of the existence of the electrostatic potential, the entropy production rate is shown to be smaller than that of the Schwarzschild black hole. 相似文献

In this paper, we extend Zhang and Zhao's recent work to the black
hole with a mass-quadruple moment. The behaviour of the tunnelling
massive particles is investigated, and the emission rate at which
massive particles tunnel across the event horizon of the black hole
is calculated. The result is consistent with an underlying unitary
theory, and takes the same functional form as that of a massless
particle. 相似文献

The stability of the Schwarzschild black hole is restudied in the Painlevé
coordinates. Using the Painlevé time coordinate to define the initial time, we
reconsider the odd perturbation and find that the Schwarzschild black hole in the
Painlevé coordinates is unstable. The Painlevé metric in this paper
corresponds to the white-hole-connected region of the Schwarzschild black hole
(r>2m) and the odd perturbation may be regarded as the angular perturbation.
Therefore, the white-hole-connected region of the Schwarzschild black hole is
unstable with respect to the rotating perturbation. 相似文献

We study the absorption probability and Hawking radiation of the scalar field in a d-dimensional black hole with quantum correction arising from the polymer quantization. We find that the quantum length scale k (i.e., the bounce radius) modifies the standard results in greybody factors and Hawking radiation on the brane and into the bulk. For the black hole with the larger mass M the effects of the parameter k in the four-dimensional black hole spacetime are entirely different from those in the high dimensional cases. When the mass of black hole M becomes very small, we also find that only the sign of the change rate of the greybody factors on the brane with respect to the dimensional number depends sharply on the bounce radius k. These information can help us know more about the extra dimension and the black holes with quantum correction. 相似文献

Hawking radiation from the with a global monopole via Schwarzschild black hole gravitational anomaly 下载免费PDF全文
This paper derives the Hawking flux from the Schwarzschild black hole with a global monopole by using Robinson and Wilczek's method. Adopting a dimensional reduction technique, it can describe the effective quantum field in the (3 + 1)-dimensional global monopole background by an infinite collection of the (1 + 1)-dimensional massless fields if neglecting the ingoing modes near the horizon, where the gravitational anomaly can be cancelled by the (1 + 1)- dimensional black body radiation at the Hawking temperature. 相似文献

We present a short and direct derivation of Hawking radiation by using the Damour-Ruffini method, as taking into account the self-gravitational interaction from the Kerr black hole. It is found that the radiation is not exactly thermal, and because the derivation obeys conservation laws, the non-thermal Hawking radiation can carry information from the black hole. So it can be used to explain the black hole information paradox, and the process satisfies unitary. 相似文献

By introducing a new tortoise coordinate transformation, we investigate the quantum thermal and non-thermal radiations of a non-stationary Kerr--Newman--de Sitter black hole. The accurate location and
radiate temperature of the event horizon as well as the maximum energy of the non-thermal radiation are derived. It is shown that the radiate temperature and the maximum energy are related to not only the evaporation rate, but also the shape of the event horizon, moreover the maximum energy depends on
the electromagnetic potential. Finally, we use the results to reduce the non-stationary Kerr--Newman black hole, the non-stationary Kerr black hole, the stationary Kerr--Newman--de Sitter black hole, and the static Schwarzshild black hole. 相似文献

We investigate the Hawking radiation of a Kaluza-Klein black hole by using one-dimensional(1D),non-equilibrium,Landauer transport model.The derived Hawking radiation temperature is in consistence with that obtained by using the usual anomaly method.With the Landauer transport model,we calculate the entropy flow out of the Kaluza-Klein black hole and the relevant entropy production rate.How these quantities depending on the physical parameters of the black hole is also discussed. 相似文献
