标题： Quantum corrected Einstein-Yang-Mills black holes in semiclassical gravity

摘要： 我们通过在场方程中包含重整化能动张量的期望值，在半经典引力中研究爱因斯坦-杨-米尔斯（EYM）黑洞。 我们自洽地求解场方程和运动方程。 此框架之前已被用于研究真空解，即量子修正的施瓦茨希尔德黑洞。 在我们包含黑洞毛发的系统中，我们发现量子修正的解，在这些解中经典视界消失并被虫洞结构取代，类似于在真空中发现的情况。 我们还发现量子修正的解，在这些解中经典视界消失，但没有虫洞结构。 我们的结果表明，在半经典引力中包含黑洞毛发仍然会导致静态球对称系统中非极端黑洞的经典视界消失。 显示英文摘要

摘要： We study Einstein-Yang-Mills (EYM) black holes in semiclassical gravity by including in the field equations the expectation value of a renormalized energy-momentum tensor in the Polyakov approximation. We solve the field equations and the equations of motion self-consistently. This framework has previously been used to study vacuum solutions, i.e. quantum corrected Schwarzschild black holes. In our system, which contains black hole hair, we find quantum corrected solutions in which the classical horizon disappears and is replaced by a wormhole structure, similarly to what is found in vacuum. We also find quantum corrected solutions in which the classical horizon disappears, but there is no wormhole structure. Our results indicate that the inclusion of black hole hair in semiclassical gravity still leads to the disappearance of classical horizons for nonextremal black holes in static spherically symmetric systems.
