Equivalence of scalar-tensor theories and scale-dependent gravity
Philipp Neckam, Christian Käding, Benjamin Koch +4
We present a novel equivalence between scale-dependent gravity and scalar-tensor theories that have only a single scalar field with a canonical kinetic term in the Einstein frame a…
Geodesics in Quantum Gravity
Benjamin Koch, Ali Riahinia, Angel Rincon
We investigate the motion of test particles in quantum-gravitational backgrounds by introducing the concept of q--desics, quantum-corrected analogs of classical geodesics. Unlike s…
Quantum Uncertainties of Static Spherically Symmetric Spacetimes
Benjamin Koch, Ali Riahinia
We present a canonical quantization framework for static spherically symmetric spacetimes described by the Einstein-Hilbert action with a cosmological constant. In addition to reco…
Quasi-normal modes and shadows of scale-dependent regular black holes
Benjamin Koch, Gonzalo J. Olmo, Ali Riahinia +2
In this paper we investigate how a regular scale-dependent black hole, characterized by a single extra parameter , behaves under perturbations by a test field (quasi-normal mode…
A Universe from a Lagrangian Fixed Point
Pedro D. Alvarez, Benjamin Koch, Ali Riahinia +1
In this paper, we investigate the theoretical possibility that a Lagrangian fixed point, when applied to cosmological models, can drive dynamical evolution towards a bouncing unive…
