Time evolution of density matrices as a theory of random surfaces
Carlo Pagani, Martin Reuter
In the operatorial formulation of quantum statistics, the time evolution of density matrices is governed by von Neumann's equation. Within the phase space formulation of quantum me…
On the possibility of a novel (A)dS/CFT relationship emerging in Asymptotic Safety
Renata Ferrero, Martin Reuter
Quantum Einstein Gravity (QEG), nonperturbatively renormalized by means of a certain asymptotically safe renormalization group (RG) trajectory, is explored by solving its scale dep…
The Spectral Geometry of de Sitter Space in Asymptotic Safety
Renata Ferrero, Martin Reuter
Within the functional renormalization group approach to Background Independent quantum gravity, we explore the scale dependent effective geometry of the de Sitter solution dS…
Background Independent Field Quantization with Sequences of Gravity-Coupled Approximants II: Metric Fluctuations
Maximilian Becker, Martin Reuter
We apply the new quantization scheme outlined in Phys. Rev. D102 (2020) 125001 to explore the influence which quantum vacuum fluctuations of the spacetime metric exert on the unive…
Towards a Geometrization of Renormalization Group Histories in Asymptotic Safety
Renata Ferrero, Martin Reuter
Considering the scale dependent effective spacetimes implied by the functional renormalization group in d-dimensional Quantum Einstein Gravity, we discuss the representation of ent…
Background Independent Field Quantization with Sequences of Gravity-Coupled Approximants
Maximilian Becker, Martin Reuter
We outline, test, and apply a new scheme for nonpertubative analyses of quantized field systems in contact with dynamical gravity. While gravity is treated classically in the prese…
