格子量子引力渐近安全性的证据
Evidence for Asymptotic Safety from Lattice Quantum Gravity
摘要：
我们计算了由欧氏动力学三角剖分定义的非微扰量子引力的谱维数。我们发现，它运行从一个值的3/2在短距离~4在大的距离尺度，类似于因果动力学三角测量的结果。我们认为，3/2的光谱维度的短距离值可以解决渐近安全性和全息原理之间的紧张关系。
英文摘要：
We calculate the spectral dimension for nonperturbative quantum gravity defined via Euclidean dynamical triangulations. We find that it runs from a value of ~3/2 at short distance to ~4 at large distance scales, similar to results from causal dynamical triangulations. We argue that the short distance value of 3/2 for the spectral dimension may resolve the tension between asymptotic safety and the holographic principle.
