Do we Observe Quantum Gravity Effects at Galactic Scales?
M. Reuter, H. Weyer
The nonperturbative renormalization group flow of Quantum Einstein Gravity (QEG) is reviewed. It is argued that there could be strong renormalization effects at large distances, in…
Newton's Constant isn't constant
Martin Reuter
This article contains a brief pedagogical introduction to various renormalization group related aspects of quantum gravity with an emphasis on the scale dependence of Newton's cons…
Background-Quantum Split Symmetry and Phase-Space Path-Integrals
M. Reuter
Phase-space path-integrals are used in order to illustrate various aspects of a recently proposed interpretation of quantum mechanics as a gauge theory of metaplectic spinor fields…
Weyl-Invariant Quantization of Liouville Field Theory
M. Reuter
Liouville field theory is quantized by means of a Wilsonian effective action and its associated exact renormalization group equation. For , an approximate solution of this equ…
