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

Varun Kher: Matter Spectral Functions from Quantum Gravity


Seminar Date:

We present a Lorentzian quantum gravity study coupled to a template matter sector with gauge fields, scalars and fermions. Provided quantum gravity offers an asymptotically safe UV-completion, we determine the photon and scalar two-point functions in the presence of gravitational fluctuations, and show that both pos...

Jesse van der Duin and Renate Loll: Effective topology of quantum spacetime


Seminar Date:

According to long-standing folklore, spacetime at Planckian distances bears no resemblance to the spacetime of classical general relativity, but instead is some kind of “quantum foam”, due to strong quantum fluctuations. Turning this handwaving concept into physical theory requires a nonperturbative, quantitative mo...
