论文摘要
我们计算在多达四个度量衍生物的一般截断中计算量子流动方程的缩放溶液。它们将渐近的紫外线固定点(扰动理论都可以访问)连接到非扰动红外区域。对于重新分布的重力理论,这种缩放溶液的存在是必要的。如果提出的缩放溶液已被确认超出我们的近似渐近自由度,则是渐近安全性的可行替代品。
We compute scaling solutions of functional flow equations for quantum gravity in a general truncation with up to four derivatives of the metric. They connect the asymptotically free ultraviolet fixed point, which is accessible to perturbation theory, to the non-perturbative infrared region. The existence of such scaling solutions is necessary for a renormalizable quantum field theory of gravity. If the proposed scaling solution is confirmed beyond our approximations asymptotic freedom is a viable alternative to asymptotic safety for quantum gravity.
