On harvesting physical predictions from asymptotically safe quantum field theories
Frank Saueressig, AgustÃn Silva
Asymptotic safety is a powerful mechanism for obtaining a consistent and predictive quantum field theory beyond the realm of perturbation theory. It hinges on an interacting fixed…

Emergence of inflaton potential from asymptotically safe gravity
AgustÃn Silva
The Asymptotic Safety Hypothesis for gravity relies on the existence of an interacting fixed point of the Wilsonian renormalization group flow, which controls the microscopic dynam…

Scalar curvature for metric spaces: Defining curvature for Quantum Gravity without coordinates
AgustÃn Silva, Jesse van der Duin
Geometrical properties of spacetime are difficult to study in nonperturbative approaches to quantum gravity like Causal Dynamical Triangulations (CDT), where one uses simplicial ma…
