Diffeomorphism-invariant Approach to Asymptotically Safe Quantum Gravity
Friederike Ihssen, Benjamin Knorr, Silas Mezger +2
We provide a novel diffeomorphism-invariant approach to asymptotically safe metric quantum gravity. It is based on physics-informed renormalisation group flows with a renormalisati…
Towards Two-to-Two Scattering of Scalars in Asymptotically Safe Quantum Gravity
Angelo P. Chiesa, Jan M. Pawlowski, Manuel Reichert
We compute the graviton-mediated two-to-two scattering amplitude and cross section for scalar particles in asymptotically safe quantum gravity. Specifically, we compute the full mo…
Self-consistent graviton spectral function in Lorentzian quantum gravity
Jan M. Pawlowski, Manuel Reichert, Jonas Wessely
We present the first fully self-consistent computation of the graviton spectral function in quantum gravity, using the spectral renormalisation group for gravity put forward in arX…
Comment on Path integral measure and RG equations for gravity
Aaron Held, Benjamin Knorr, Jan M. Pawlowski +4
Asymptotic safety is a candidate for a predictive quantum theory of gravity and matter. Recent works (arXiv:2412.10194 and arXiv:2412.14108) challenged this scenario. We show that…
Visions in Quantum Gravity
Luca Buoninfante, Benjamin Knorr, K. Sravan Kumar +36
To deepen our understanding of Quantum Gravity and its connections with black holes and cosmology, building a common language and exchanging ideas across different approaches is cr…
The Absolute Swampland
Astrid Eichhorn, Arthur Hebecker, Jan M. Pawlowski +1
The ``Swampland Program'' aims to discriminate consistent-looking effective field theories that do not admit a UV completion in quantum gravity from those that do. While most often…
Quantum Gravity from dynamical metric fluctuations
Jan M. Pawlowski, Manuel Reichert
In this contribution, we discuss the asymptotic safety scenario for quantum gravity by evaluating the correlation functions of dynamical metric fluctuations. This is done with a fu…
Effective action and black hole solutions in asymptotically safe quantum gravity
Jan M. Pawlowski, Jan Tränkle
We derive the quantum effective action and the respective quantum equations of motion from multi-graviton correlation functions in asymptotically safe quantum gravity. The fully mo…
Universal gravitational-wave signatures from heavy new physics in the electroweak sector
Astrid Eichhorn, Johannes Lumma, Jan M. Pawlowski +2
We calculate the gravitational-wave spectra produced by the electroweak phase transition with TeV-scale Beyond-Standard-Model physics in the early universe. Our study captures the…
