Extending Parikh and Wilczek's work to the non-stationary black hole, we study the Hawking radiation of the non-stationary Kerr black hole by the Hamilto-Jacobi method. The result shows that the radiation spectrum is not purely thermal and the tunnelling probability is related to the change of Bekenstein Hawking entropy, which gives a correction to the Hawking thermal radiation of the black hole. 相似文献

Extending Parikh and Wilczek's work to the non-stationary black hole, we discuss the Hawking radiation of the slowly varying Reissner-NordstrSm black hole by considering the unfixed background spacetime and the selfgravitation interaction. The result shows that the tunnelling rate is related to both the variation of BekensteinHawking entropy and the radiation spectrum deviating from the purely thermal one. This is in agreement with Parikh and Wilczek's result. Then a new method to study Hawking radiation of the non-stationary black holes is presented. 相似文献

Based on the anomaly cancellation method, initiated by Robinson and Wilczek, we investigates Hawking radiation from the modified Schwarzschild black hole from gravity's rainbow from the anomaly point of view. Unlike the general Schwarzschild space-time, the metric of this black hole depends on the energies of probes. The obtained result shows to restore the underlying general covariance at the quantum level in the effective field, the covariant compensating flux of energy-momentum tensor, which is related to the energies of the probes, should precisely equal to that of a (1 + 1)-dimensional blackbody at the Hawking temperature. 相似文献

The quantum tunnelling radiation of Schwarzschild de Sitter black hole with a global monopole 总被引:1,自引:0,他引:1 下载免费PDF全文
Applying Parikh's quantum tunnelling method, this paper has studied the quantum
tunnelling radiation of Schwarzschild de Sitter black hole with a global monopole.
The result shows that the tunnelling rates at the event horizon and the cosmological
horizon are related to Bekenstein--Hawking entropy and the derived radiation
spectrum is not precisely thermal when considering energy conservation and
self-gravitation interaction. 相似文献

The Hawking radiation of the charged particle via tunnelling from the axisymmetric Sen black hole 下载免费PDF全文
Extending Parikh's semi-classical quantum tunnelling model, this paper has studied
the Hawking radiation of the charged particle via tunnelling from the horizon of the
axisymmetric Sen black hole. Different from the uncharged massless particle, the
geodesics of the charged massive particle tunnelling from the horizon is not
light-like. The derived result supports Parikh's opinion and provides a correct
modification to Hawking strictly thermal spectrum developed by the fixed background
space-time and not considering the energy conservation and the self-gravitation
interaction. 相似文献

A New Method to Study Hawking Radiation of Charged Particle from Stationary Axisymmetric Sen Black Hole 下载免费PDF全文
Taking the self-gravitation interaction and energy conservation,charge conservation and angular momentum conservation into accpunt, we discuss the tunnelling characteristics of the charged particle from Sen black hole by the Hamilton-Jacobi method. The result shows that the tunnelling probability is related to the change of Bekenstein-Hawking entropy, and the actual radiation spectrum deviates from the pure thermal one, which is consistent with the result of Parikh and Wilczek and gives a new method to correct the Hawking pure thermal spectrum of Sen black hole. 相似文献
