We use the non-Gaussian fixed points (NGFPs) appearing in the renormalization group flow of gravity and gravity-matter systems to construct models of NGFP-driven inflation via a renormalization group improvement scheme. The cosmological predictions of these models depend sensitively on the characteristic properties of the NGFPs, including their position and stability coefficients, which in...

What should a fundamental theory of quantum gravity look like? While the theories united in the Standard Model of particle physics fulfill a standard set of requirements, gravity is special in the sense that spacetime itself becomes dynamical.
The independence of any preset background geometry is thus at the root of every quantum generalization of general relativity, as is (nonperturbative)...
