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…
Renormalization group flows into phases with broken symmetry
Manfred Salmhofer, Carsten Honerkamp, Walter Metzner +1
We describe a way to continue the fermionic renormalization group flow into phases with broken global symmetry. The method does not require a Hubbard-Stratonovich decoupling of the…
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…
