The Asymptotic Safety Program: New results and an inconvenient truth
Speaker(s): Martin Reuter
Abstract: We briefly review the various components and their conceptual status of the full Asymptotic Safety Program which aims at finding a nonperturbative infinite-cutoff limit of a regularized functional integral for a quantum field theory of gravity. It is explained why in the continuum formulation based ... read more

Effective field theory framework in QG
Abstract: Gravity Induced Grand UnificationMotivated by the lack of evidence for physics beyond the Standard Model in the TeV region, we discussed an alternative path for grand unification. We show that simple grand unification models based on e.g. SU(5) can work successfully even without low scale supersymme... read more

Dynamical Dimensional Reduction
Abstract: Dynamical dimensional reduction and Asymptotic SafetyThe effective average action approach to Quantum Einstein Gravity (QEG) is discussed as a natural framework for exploring the scale dependent Riemannian geometry and multifractal micro-structure of the effective spacetimes predicted by QEG. Their ... read more

Quantum gravity at astrophysical distances
Speaker(s): Martin Reuter
Abstract: In this talk we assume that Quantum Einstein Gravity (QEG) is the correct theory of gravity on all length scales. We use both analytical results from nonperturbative renormalization group (RG) equations and experimental input in order to describe the special RG trajectory of QEG which is realized in... read more
