Abstract |
In the asymptotic safety scenario, the ultraviolet behaviour of gravity and therefore the very early stages of cosmology are controlled by a non-Gaussian fixed point of the renormalisation group flow. I will present a possible scenario how renormalisation group running modifies the dynamics of a Friedmann-Robertson-Walker universe with scalar matter fields and how the evolution away from the renormalisation group fixed point looks like. I will also give conditions under which cosmological perturbations with the correct properties can be obtained. |
