论文摘要
基本物理参数的比例依赖性是普通量子场理论的一般特征。当应用于重力时，这种想法会产生有效的动作，该动作通常包含牛顿耦合常数，从中可以推断出新的（球形对称）黑洞的空位。当然，作为最少有用的要求，新的指标应与大径向坐标处的Schwarzschild场相匹配。通过进一步征收新的量表依赖度度量，与Donoghue量子校正的电位匹配的简单请求，我们发现尚未探索的黑洞时空，自然而然地描述了所谓的Planck恒星。
Scale dependence of fundamental physical parameters is a generic feature of ordinary quantum field theory. When applied to gravity, this idea produces effective actions generically containing a running Newtonian coupling constant, from which new (spherically symmetric) black hole spacetimes can be inferred. As a minimum useful requirement, of course, the new metrics should match with a Schwarzschild field at large radial coordinate. By further imposing to the new scale dependent metric the simple request of matching with the Donoghue quantum corrected potential, we find a not yet explored black hole spacetime, which naturally turns out to describe the so-called Planck stars.
