Since Parikh and Wilczek proposed a semiclassical tunneling method to investigate the Hawking radiation of static and spherically symmetric black holes, the method has been extensively developed to study various black holes. However, in almost all of the subsequent papers, there exists a important shortcoming that the geodesic equation of the massive particle is defined inconsistently with that of the massless particle. In this paper, we propose a new idea to reinvestigate the tunneling radiation from the event horizon of the Reissner-Nordström black hole. In our treatment, by starting from the Lagrangian analysis on the action, we redefine the geodesic equation of the massive and massless particle via tunneling from the event horizon of the Reissner-Nordström black hole, which overcomes the shortcoming mentioned above. The highlight of our work is a new and important development for the Parikh-Wilczek’s semiclassical tunneling method. 相似文献

Based on the generalized uncertainty principle, in which the quantum gravitational effects are properly taken in to account, the corrected Bekenstein-Hawking entropy of the higher dimensional Reissner-Nordström black hole, up to the square order of Planck length, has been calculated. Using the corrected entropy, the black hole radiation probability has been calculated in the tunneling formalism, which is corrected up to the same order of the Planck length and a generalized quantum tunneling through the event horizon of the black hole is obtained. 相似文献

Although the tunneling approach is fully established for black hole radiation, much work has been done to support the extension
of this approach to more general settings. In this letter the Parikh-Kraus-Wilczeck tunneling proposal of black hole tunneling
radiation is considered. The Reissner-Nordstr?m-de Sitter black hole thermodynamics is studied according to the generalized
uncertainty principle and the modified dispersion relation analysis. It is shown that entropy, temperature and the original
Parikh-Kraus-Wilczek calculations of the black hole tunneling probability receive new corrections. The results are compared
and it is shown that these two alternative approaches lead to the same results if one uses the suitable expansion coefficients. 相似文献

We extended the Parikh-Wilczek’s method to calculate the tunneling radiation of charged and magnetized particles from the
event horizon and the cosmological horizon of the Reissner-Nordstr?m-de Sitter black hole with magnetic charges. We reconstructed
the electromagnetic field tensor and recalculated the Lagrangian of the field corresponding to the source with electric and
magnetic charges. By viewing the eclectic and magnetic charges as an equivalent electric charge, we obtained the tunneling
rate of the charged and magnetized particles. Our calculation supports the conclusion given by Parikh and Wilczek that the
emission spectrum is no longer purely thermal, and the emission process supports the information conservation. 相似文献

Using Damour-Ruffini’s method, the massive charged particles’ Hawking radiation from a Reissner-Nordström black hole is investigated. When the back-reaction of particles’ energy and charge to spacetime is considered, we get the unthermal spectrum. It is possible that the information will get out from the black hole with the corrected spectrum. It can be used to explain the information loss paradox, and the underlying unitary theory will be satisfied. The same conclusion as the works finished before can be drawn. However, our work is different from them, and the method is more simple and explicit. 相似文献

Dirac Quasinormal Modes of the Schwarzschild-anti-de Sitter Black Hole with a Global Monopole 下载免费PDF全文
The quasinormal modes associated with the decay of Dirac field perturbation around a Schwarzschild-anti-de Sitter black hole with a global monopole (SAdSBHGM) are calculated using the Horowitz-Hubeny approach. For the large SAdSBHGM, we find that η has little effect on the quaslnormal frequencies. However, for the intermediate and small SAdSBHGM, in the limit η→1/√8π, the real parts of the fundamental quasinormal frequencies approximate the linear functions of Tand the imaginary ones approximate the linear functions of r+. 相似文献

When a black hole radiates particles, it losses energy and shrinks, the horizon contracts from its original radius to a new smaller radius. This leads to the separation between the initial and final radii, which sets the barrier for the particles to tunnel We develop the work of Parikh [Phys. Rev. Lett. 85 (2000) 5042; Gen. Rel. Grav. 36 (2004) 2419] to a Horowitz-Strominger black hole, i.e. applying the Wentzel-Kramers-Brillouin approximation and semi-classical method to calculate the rate of the Hawking radiation. The result agrees with Г~e^-21mf=e^△SBH. It is also proven that the energy spectrum deviates from exact thermality. 相似文献

In some recent derivations thermal characters of the inner horizon have been employed; however, the understanding of possible role that may play the inner horizons of black holes in black hole thermodynamics is still somewhat incomplete. Motivated by this problem we investigate Hawking radiation of the Reissner-Nordström-Taub-NUT (RNTN) black hole by considering thermal characters of both the outer and inner horizons. We apply Damour-Ruffini method and the thin film brick wall model to calculate the temperature and the entropy of the inner horizon of the RNTN black hole. The inner horizon admits thermal character with positive temperature and entropy proportional to its area, and it thus may contribute to the total entropy of the black hole in the context of Nernst theorem. Considering conservations of energy and charge and the back-reaction of emitting particles to the spacetime, the emission spectra are obtained for both the inner and outer horizons. The total emission rate is the product of the emission rates of the inner and outer horizons, and it deviates from the purely thermal spectrum and can bring some information out. Thus, the result can be treated as an explanation to the information loss paradox. 相似文献

Applying quantum tunneling method, this paper has studied the Hawking radiation of Garfinkle-Horowitz-Stromingen dilaton black
hole. In this way, the emission rates of massless particles and massive particles tunneling across the event horizon of black
holes is obtained. The result shows that the radiation spectrum of these two different kinds of outgoing particles is related
to the change of Bekenstein-Hawking entropy, which is no longer precisely thermal. 相似文献

Extending Parikh-Wilczek’s semi-classical tunneling method, we discuss the Hawking radiation of the charged massive particles via tunneling from the cosmological horizon of (n+2)-dimensional Topological Reissner-Nordström-de Sitter black hole.The result shows that, when energy conservation and electric charge conservation are taken into account, the derived spectrum deviates from the pure thermal one, but satisfies the unitary theory, which provides a probability for the solution of the information loss paradox. 相似文献

The recent work of Robinson and Wilczek that Hawking radiation can be determined by the compensating fluxes is extended to the charged and magnetized Reissner-Nordström de Sitter black hole. We reconstruct the electromagnetic field tensor and the Lagrangian of the field corresponding to the source with electric and magnetic charges to redefine an equivalent charge and gauge potential. We construct the effect field theory between the event horizon and cosmological horizon to respectively determine the compensating fluxes from them, which are shown to exactly equal to those of Hawking radiation, by the covariant anomaly cancellation conditions. 相似文献

Hawking radiation from the cylindrical symmetric black hole, which is asymptotically anti-de Sitter not only in the transverse
direction but also in the string or membrane direction, is discussed from the anomaly point of view. We implement the covariant
anomaly cancellation method, the more refined formalism that was proposed by Banerjee and Kulkarni recently than the initial
work of Robinson et al., to discuss the near-horizon gauge and gravitational anomalies. Our result shows that Hawking radiation
from the cylindrical configurations with horizons also can be reproduced by the anomaly cancellation method. 相似文献

We extend Parikh's study to the non-stationary black hole. As an example of the non-stationary black hole, we investigate the tunnelling effect and Hawking radiation from a Vaidya black hole whose Bondi mass is identical to its mass parameter. The Hawking radiation is considered as a tunnelling process across the event horizon and we calculate the tunnelling probability. It is found that the is the function of Bondi mass re(υ). result is different from Parikh's study because dr H/dυ 相似文献

Hawking evaporation of photons in a Vaidya–de Sitter black hole is investigated by using the method of generalized tortoise coordinate transformation. Both the location and the temperature of the event horizon depend on the time. It is shown that Hawking radiation of photons exists only for the complex Maxwell scalar 0 in the advanced Eddington–Finkelstein coordinate system. This asymmetry of Hawking radiation for different components of Maxwell fields probably arises from the asymmetry of spacetime in the advanced Eddington–Finkelstein coordinate system. It is shown that the black body radiant spectrum of photons resembles that of Klein–Gordon particles. 相似文献

Considering energy conservation and the backreaction of particles to spacetime, we investigate the massless/massive Dirac particles' Hawking radiation from a Schwarzschild black hole, The exact expression of the emission rate near the horizon is obtained and the result indicates that Hawking radiation spectrum is not purely thermal. The result obtained is consistent with the results obtained before. It satisfies the underlying unitary theory and offers a possible mechanism to explain the information loss paradox. Whereas the improved Damour-Rufflni method is more concise and understandable, 相似文献

Quantum Tunnelling and Hawking Radiation of Schwarzchild-Anti-de Sitter Black Hole with Topological Defect 下载免费PDF全文
We extend Parikh's recent work to Schwarzchild-anti-de Sitter black hole with topological defect whose Arnowitt-Deser-Misner (ADM) mass is no longer identical to its mass parameter. We view the Hawking radiation as a tunnelling process across the event horizon and the cosmological horizon. From the tunnelling probability, we find a leading correction to the semi-classical emission rate. The result employs an underlying unitary theory. 相似文献

Hawking radiation of NUT-Kerr-Newman de Sitter black hole is studied via anomalous point of view in this paper. The results
show that the charged current and energy-momentum tensor fluxes, to restore gauge invariance and general coordinate covariance
at the quantum level in the effective field theory, are exactly equal to those of Hawking radiation from the event horizon
(EH) and the cosmological horizon (CH) of NUT-Kerr-Newman de Sitter black hole, respectively. 相似文献

Hawking radiation of a particle with electric and magnetic charges from the Kerr-Newman-Kasuya black hole is discussed in
the dragging coordinate frame via the anomaly cancellation method, initiated by Robinson and Wilczek. We redefine an equivalent
charge of the charged and magnetized black hole by reconstructing the electromagnetic field tensor. We adopt the refined covariant
anomaly cancellation method to determining the compensating fluxes of charge flow and energy momentum tensor, which are proved
to precisely match with those of the 2-dimensional blackbody radiation at the Hawking temperature with an appropriate chemical
potential. 相似文献

The Kerner-Mann fermions tunneling framework is extended to the spin particles with electric and magnetic charges in this
paper. We rewrite the electromagnetic field tensor and the Lagrangian of the field corresponding to the source with electric
and magnetic charges to redefine an equivalent charge. We only consider the case that the ratio of the electric charge and
magnetic charge of the emission is constant and equal to the source. The result shows that when the energy conservation together
with the electric charge and magnetic charge conservations are taken into account in the dynamical background space time,
the emission rate agrees with the underlying unitary theory and the actual radiation spectrum of charged and magnetized fermions
also derivates from the pure thermal one. 相似文献
