Description
Geometrical information of the quantum spacetime which we try to observe is crucially carried by physical fields. Geometrical observables cannot be properties of the “quantum spacetime” alone, but must also depend on the experimental setup that is used in order to observe or probe them. Every physics-based geometry will depend on the observer, and I will present two examples where this is manifest: I will employ the spectral flow method as a diagnostic tool to identify the scale-dependent field modes that participate in the geometric effective field theory; furthermore, I will present an approach to compute the RG flow of running relational observables in asymptotically safe quantum gravity.
