标题： Black hole solutions in quantum phenomenological gravitational dynamics

摘要： 我们研究了基于Alonso-Serrano和Liška发展的时空热力学的量子引力现象学方法中的黑洞解。 场方程是迹为零的，类似于单模重力，且包括二次曲率修正。 我们发现该理论中的静态球对称真空时空分为两个分支。 第一分支与单模重力中的相应解无法区分，描述的是施瓦西（反）德西特黑洞。 而第二分支则描述了无视界的解，并以较大的空间曲率值为特征。 我们分析了两个分支上的首阶度规扰动的动力学，表明在此层次上不存在偏离单模重力的现象。 显示英文摘要

摘要： We investigate black hole solutions within a phenomenological approach to quantum gravity based on spacetime thermodynamics developed by Alonso-Serrano and Li\v{s}ka. The field equations are traceless, similarly to unimodular gravity, and include quadratic curvature corrections. We find that static, spherically symmetric, vacuum spacetimes in this theory split into two branches. The first branch is indistinguishable from corresponding solutions in unimodular gravity and describes Schwarzschild-(Anti) de Sitter black holes. The second branch instead describes horizonless solutions and is characterized by large values of the spatial curvature. We analyze the dynamics of first-order metric perturbations on both branches, showing that there are no deviations from unimodular gravity at this level.
