Recent research shows that Hawking radiation from black hole horizon can 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 γ^μ 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 by constructing a set of appropriate matrices γ^μ 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

Spectroscopy via adiabatic covariant action for the Baados-Teitelboim-Zanelli (BTZ) black hole 下载免费PDF全文
Very recently, via the covariant form of the adiabatic invariant I =∮pidqi instead of I =∫pidqi , an equally spaced spectroscopy of a Schwarzschild black hole was derived. The emphasis was given to the covariant of results. In this paper, we extend that work in a spherically symmetric spacetime to the case of a rotating Baados-Teitelboim-Zanelli (BTZ) black hole. It is noteworthy that the adiabatic covariant action I =∮pidqi gives the same value for the black hole spectroscopy in different coordinates. The result shows that the area spectrum is A = 8πl2P , which confirms Bekenstein's initial proposal. And the result is consistent with that already obtained by other methods. 相似文献

对稳态NUT- Kerr-Newman黑洞的量子隧穿特征的研究 总被引:1,自引:1,他引:0
运用Parikh的量子隧穿模型, 研究了NUT- Kerr- Newman黑洞的量子隧穿辐射特征. 研究结果表明, 当考虑能量守恒与角动量守恒时, 稳态NUT- Kerr- Newman黑洞的真实谱不再是纯热谱, 视界处粒子的隧穿率与Bekenstein-Hawking熵有关, 且满足量子力学中的幺正性原理. 相似文献
