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

Zois Gyftopoulos: Quark and lepton mixing in the Asymptotic Safe Standard Model


Seminar Date:

In this talk, I will explore the phenomenological consequences of Quantum Scale symmetry in the matter sector of the Standard Model with Asymptotically Safe Quantum Gravity. In particular, trans-Planckian quantum scale symmetry in the matter sector induced by Asymptotically Safe Quantum Gravity, leaves an imprint on...

Jonas Wessely: Self-consistent graviton spectral function in Lorentzian quantum gravity


Seminar Date:

We present the first fully self-consistent computation of the graviton spectral function in (asymptotically safe) quantum gravity, using the spectral renormalisation group within a physical mass-shell renormalisation scheme. Self-consistency here means that the full non-perturbative spectral function, including the ...

Jose Padua-Arguelles: Non-Perturbative S-matrix Renormalization


Seminar Date:

I will present our recent proposal of a renormalization group flow equation for a functional that generates S-matrix elements and which captures similarities to the well-known Wetterich and Polchinski equations. While the latter ones respectively involve the effective action and Schwinger functional, which are genui...

Axel Maas: Looking for geons


Seminar Date:

Geons are hypothetical objects from self-bound gravity quanta. They are potential candidates for dark matter, but could also be considered (quantum) black holes, and could be actually be constituents of macroscopical black holes.
