The international seminar on asymptotic safety was founded in spring 2011, with the intention of bringing the asymptotic-safety community together, and providing a platform for talks on asymptotic safety in and beyond quantum gravity, as well as related topics in quantum gravity and quantum field theory.

Upcoming seminars

Ivano Basile: String Tension between de Sitter vacua and Curvature Corrections


Seminar Date:

Preliminary abstract: Higher-derivative corrections to cosmological effective actions in string theory are largely constrained by T-duality, but have been computed hitherto only to the first few orders in the string scale α′. The functional renormalization group, in conjunction with the strong constraints imposed by...

Tobias Denz: Reconstructing the graviton


Seminar Date:

Preliminary abstract: We reconstruct the Lorentzian graviton propagator in asymptotically safe quantum gravity from Euclidean data. The reconstruction is applied to both the dynamical fluctuation graviton and the background graviton propagator. We prove that the spectral function of the latter necessarily has negati...

Astrid Eichhorn

Astrid is an Associate Professor at CP3-Origins, University of Southern Denmark, Villum Young Investigator and Perimeter Institute Visiting Fellow. She works on building connections in quantum gravity: connections between quantum-gravity approaches, connections between fundamental theory and phenomenology, and connections between neighboring research communities. more
