摘要

本文研究了膜世界中原始黑洞的热力学性质。具体来说,研究人员检查了霍金辐射和PBH的寿命。通过他们的分析,导出了贝肯斯坦-霍金熵、温度和热容的精确解析表达式。他们的发现表明,早期宇宙中PBH的寿命至少减少了一个数量级,最终导致它们的蒸发。这可以解释为什么我们在最近的宇宙时代没有观察到PBH的最终快速蒸发。

Hawking Radiation and Lifetime of Primordial Black Holes in Braneworld
The paper explores the thermodynamic properties of primordial black holes (PBHs) in the braneworld. Specifically, the researchers examined Hawking radiation and the lifetime of PBHs. Through their analysis, an exact analytical expression for the Bekenstein–Hawking entropy, temperature, and heat capacity was derived. Their findings suggest that the lifetime of PBHs in the early universe is reduced by at least one order of magnitude, ultimately leading to their evaporation. This could explain why we have not observed the final rapid evaporation of PBHs in the recent epoch of the universe.
