Semantic Scholar uses AI to extract papers important to this topic.
In the asymptotic safety paradigm, a quantum field theory reaches a regime with quantum scale invariance in the ultraviolet… Expand This thesis aims to identify the key features of the asymptotic safety scenario and discuss how it could provide a well-defined… Expand The asymptotic safety scenario of gravity conjectures that i) the quantum field theory of gravity exists thanks to the presence… Expand Abstract Asymptotic safety describes a scenario in which general relativity can be quantized as a conventional field theory… Expand We give a pedagogical introduction to the basic ideas and concepts of the Asymptotic Safety program in quantum Einstein gravity… Expand We investigate the high-energy properties of matter theories coupled to quantum gravity. Specifically, we show that quantum… Expand We compute the ghost anomalous dimension within the asymptotic-safety scenario for quantum gravity. For a class of covariant… Expand In the average action approach to the quantization of gravity the fundamental requirement of "background independence" is met by… Expand These lecture notes provide a pedagogical introduction to a specific continuum implementation of the Wilsonian renormalization… Expand Four-dimensional Quantum Einstein Gravity (QEG) is likely to be an asymptotically safe theory which is applicable at arbitrarily… Expand
