量子引力的几种方法表明,在普朗克体系中,在低能量下探测的四维时空的标准描述被光谱维为2的时空所取代。相对论对称性的含义可能是重大的,事实上,在霍拉瓦-利夫希茨引力中发现的谱维“运行”的最切实的图像,需要惯性系的相对论的崩溃。在这封信中,我们将运行光谱尺寸的情况下,不需要出现一个首选帧。我们认为,最好的研究机制变形相对论对称性,同时保持惯性系的相对性,在普朗克尺度的曲率动量空间的基础上。我们明确地表明,如何运行的光谱尺寸可以从这些模型。
Several approaches to quantum gravity suggest that the standard description of spacetime as probed at low-energy, with four dimensions, is replaced in the Planckian regime by a spacetime with a spectral dimension of two. The implications for relativistic symmetries can be momentous, and indeed the most tangible picture for “running” of the spectral dimension, found within Horava–Lifshitz gravity, requires the breakdown of relativity of inertial frames. In this Letter we incorporate running spectral dimensions in a scenario that does not require the emergence of a preferred frame. We consider the best studied mechanism for deforming relativistic symmetries whilst preserving the relativity of inertial frames, based on a momentum space with curvature at the Planck scale. We show explicitly how running of the spectral dimension can be derived from these models.
