On the Structure of the Vacuum in Quantum Gravity: A View from the Asymptotic Safety Scenario

Although the Asymptotic Safety scenario is one of the most promising approaches to quantum gravity, little attention has been devoted to the issue of the vacuum state. Higher derivative operators often appear on the ultraviolet critical surface around the non-Gaussian fixed point generating addition...
