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…
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…
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…
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…
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…
