Asymptotic Safety in Quantum Einstein Gravity: nonperturbative renormalizability and fractal spacetime structure

O. Lauscher, M. Reuter

The asymptotic safety scenario of Quantum Einstein Gravity, the quantum field theory of the spacetime metric, is reviewed and it is argued that the theory is likely to be nonpertur…

Fractal Spacetime Structure in Asymptotically Safe Gravity

O. Lauscher, M. Reuter

Four-dimensional Quantum Einstein Gravity (QEG) is likely to be an asymptotically safe theory which is applicable at arbitrarily small distance scales. On sub-Planckian distances i…

Flow Equation of Quantum Einstein Gravity in a Higher-Derivative Truncation

O. Lauscher, M. Reuter

Motivated by recent evidence indicating that Quantum Einstein Gravity (QEG) might be nonperturbatively renormalizable, the exact renormalization group equation of QEG is evaluated…

Towards Nonperturbative Renormalizability of Quantum Einstein Gravity

O. Lauscher, M. Reuter

We summarize recent evidence supporting the conjecture that four-dimensional Quantum Einstein Gravity (QEG) is nonperturbatively renormalizable along the lines of Weinberg's asympt…

Is Quantum Einstein Gravity Nonperturbatively Renormalizable?

O. Lauscher, M. Reuter

We find considerable evidence supporting the conjecture that four-dimensional Quantum Einstein Gravity is ``asymptotically safe'' in Weinberg's sense. This would mean that the theo…

Ultraviolet Fixed Point and Generalized Flow Equation of Quantum Gravity

O. Lauscher, M. Reuter

A new exact renormalization group equation for the effective average action of Euclidean quantum gravity is constructed. It is formulated in terms of the component fields appearing…
