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…
