论文摘要

我们根据假设的反射表面略微在外层半径外的假设反射表面,计算旋转黑洞的灰体因子和蒸发速率,假设它由于防火墙或拉伸地平线而自发地发射了热辐射。由于反射表面和角动量屏障之间的空腔引起的共振,灰体因子在频率空间中受到调制。通过考虑到中微子,光子和重力的多距离模式的这种效果,我们从数值上计算了黑洞的质量和角动量的时间发展,并表明激发的反射表面缩短了量子黑洞的寿命。

We compute the graybody factor and evaporation rate of a rotating black hole in the presence of a hypothetical reflective surface slightly outside the outer horizon radius, assuming that it spontaneously emits thermal radiation due to quantum-gravitational effects such as firewalls or stretched horizons. As a result of a resonance caused by a cavity between the reflective surface and angular momentum barrier, the graybody factor is subject to a modulation in the frequency space. By taking into account this effect for multiangular modes of neutrinos, photons, and gravitons, we numerically compute the time development of the mass and angular momentum of the black hole, and show that the excited reflective surface shortens the lifetime of quantum black holes.
