利用威尔逊重整化群研究了四维爱因斯坦 - 希尔伯特引力的相图。从非微扰的引力子传播子推导出了连接短距离处的紫外不动点和长距离处有吸引力的红外不动点的光滑轨迹。讨论了对渐近安全猜想的影响以及进一步的结果。© 2013作者。由爱思唯尔公司出版。保留所有权利。
The phase diagram of four-dimensional Einstein-Hilbert gravity is studied using Wilson's renormalization group. Smooth trajectories connecting the ultraviolet fixed point at short distances with attractive infrared fixed points at long distances are derived from the non-perturbative graviton propagator. Implications for the asymptotic safety conjecture and further results are discussed. (C) 2013 The Authors. Published by Elsevier B.V. All rights reserved.
