二次引力中的GUP黑洞残余

GUP black hole remnants in quadratic gravity

Iberê Kuntz, Roldao da Rocha

摘要:

本文研究了二次引力场中静态球对称渐近平坦解的霍金辐射。在广义不确定原理(GUP)的背景下,发射的费米子由狄拉克方程控制,该方程探索时空(量子)性质。用隧道方法和WKB方法研究了Hawking热谱。霍金通量消失的小黑洞,GUP参数和耦合常数的精确组合,驱动的引力相互作用在二次引力,产生绝对稳定的黑洞残余物。

英文摘要:

The Hawking radiation of static, spherically symmetric, asymptotically flat solutions in quadratic gravity, is here explored. The emitted fermions are governed by the Dirac equation in the generalized uncertainty principle (GUP) context, that probes the spacetime (quantum) nature. The Hawking thermal spectrum is scrutinized out of the tunnelling method and the WKB procedure. The Hawking flux is shown to vanish for small black holes, for a precise combination of the GUP parameter and the coupling constants that drive the gravitational interaction in quadratic gravity, yielding absolutely stable black hole remnants.
