Corrected Stefan-Boltzmann Law and Lifespan of a Black Hole

The corrected Stefan-Boltzmann law of black holes in the frame of a generalized uncertainty principle is derived through the Planck equation of thermal radiation. The result is different from the fiat spacetime： a corrected T term induced by the generalized uncertainty principle emerges; the coefficient of the T4 term is no longer a constant while related with the spacetime in the vicinity of the event horizon and the thin film model. Applying this corrected law to black hole radiation, the highest temperature in the final time of the radiation and the corresponding remnant with a mass of order of Planck mass are obtained. The lifespan of black holes is also corrected, however, the correction is extremely small.

Discussion on the event horizon and quantum ergosphere of dynamic rotating black holes in a tunneling framework

According to the Parikh--Wilczek tunneling framework, the locations of the local horizons of dynamic rotating black holes can be worked out. The calculations show that the quantum ergosphere of the black hole is identical with the tunneling potential barrier set by particle's tunneling across the relevant horizon. Then, some discussions on the origin of the Hawking radiation will be shown.

Tunnelling Effect and Hawking Radiation from a Vaidya Black Hole

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

New Coordinates for the Evaporating Vaidya Black Hole

Drawbacks of the ingoing Eddington-Finkelstein coordinates in describing the quantum thermal properties of the evaporating Vaidya black hole are presented. A new coordinate system we proposed previously [Acta Phys. Sin. 46 （1997） 1273] is employed. In this new coordinate system, the thermal radiation temperature of the Vaidya black hole is discussed again with the back reaction method.

临界中性Gauss-Bonnet-anti-de Sitter黑洞复杂度演化

利用Fan和Liang(Fan Z Y,Liang H Z 2019 Phys.Rev.D 100086016)研究一般高阶导数引力复杂度的方法,对临界中性Gauss-Bonnet-anti-de Sitter(Gauss-Bonnet-anti-de Sitter,AdS)黑洞的复杂度演化进行研究,并且将研究结果和一般中性Gauss-Bonnet-AdS黑洞的结果进行了比较.研究发现,二者的复杂度演化的整体规律是一致的,它们的主要区别在无量纲的临界时间上.对于五维的临界中性Gauss-Bonnet-AdS黑洞,当黑洞视界面为平面或者球面时,不同大小的黑洞的无量纲的临界时间相同,都取到了最小值.当维度超过五维时,不同大小的球对称临界中性Gauss-Bonnet-AdS黑洞的无量纲临界时间的差异明显要比一般的情况小.这些差异很可能和中性Gauss-Bonnet-AdS黑洞的临界性有关.     

Hawking radiation via tunnelling from general stationary axisymmetric black holes

Hawking radiation is viewed as a tunnelling process. In this way the emission rates of massless particles and massive particles tunnelling across the event horizon of general stationary axisymmetric black holes are calculated, separately. The emission spectra of these two different kinds of outgoing particles have the same functional form and both are consistent with an underlying unitary theory.
