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

Shouryya Ray: Towards a Higgs Mass Determination in Asymptotically Safe Gravity with a Dark Portal


Seminar Date:

There are reasons to believe that extensions to the Standard Model that tend to lower the Higgs mass are phenomenologically attractive. (For one thing, it would allow to accommodate a more stable electroweak vacuum.) Such extensions, however, usually come with a significantly enlarged number of free parameters, and ...

Focus Seminar: Black Holes in Asymptotic Safety (Frank Saueressig & Aaron Held)


Seminar Date:

Black holes are vital for a consistent description of gravitational wave events as well as the recent image of the Event Horizon Telescope. However, black holes also harbor a singularity and are thus theoretically incomplete. Presented with this exciting dichotomy, asymptotically safe quantum gravity may offer a the...

Alessio Baldazzi: Essential renormalization group


Seminar Date:

We use the generalised flow of the Effective average action which incorporates field redefinitions along the RG flow. This equation allows for the implementation of essential schemes, i.e. schemes where one can fix the value of inessential couplings. From the practical point of view, this produces simplifications in...

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
