Description
In this talk, I will briefly introduce the asymptotic-safety paradigm in quantum gravity. As an application, I will explore scalar-gravity systems to show the constraining power of asymptotic safety: the strength of the gravitational fluctuations should not exceed a critical value otherwise they generate complex fixed-point values in higher-order scalar interactions. On the other hand, within truncations of the matter-gravity dynamics, the fixed point lies beyond that critical strength unless fermions and vectors are included.
