Scale-dependent metric and causal structures in Quantum Einstein Gravity
Martin Reuter, Jan-Markus Schwindt
Within the asymptotic safety scenario for gravity various conceptual issues related to the scale dependence of the metric are analyzed. The running effective field equations implie…
Scale Dependent Metric and Minimal Length in QEG
Martin Reuter, Jan-Markus Schwindt
The possibility of a minimal physical length in quantum gravity is discussed within the asymptotic safety approach. Using a specific mathematical model for length measurements ("CO…
A Minimal Length from the Cutoff Modes in Asymptotically Safe Quantum Gravity
Martin Reuter, Jan-Markus Schwindt
Within asymptotically safe Quantum Einstein Gravity (QEG), the quantum 4-sphere is discussed as a specific example of a fractal spacetime manifold. The relation between the infrare…
The cosmological constant problem in codimension-two brane models
Jan-Markus Schwindt, Christof Wetterich
We discuss the possibility of a dynamical solution to the cosmological constant problem in the contaxt of six-dimensional Einstein-Maxwell theory. A definite answer requires an und…
Dark energy cosmologies for codimension-two branes
Jan-Markus Schwindt, Christof Wetterich
A six-dimensional universe with two branes in the "football-shaped" geometry leads to an almost realistic cosmology. We describe a family of exact solutions with time dependent cha…
Holographic Branes
Jan-Markus Schwindt, Christof Wetterich
We discuss the properties of codimension-two branes and compare them to codimension-one branes. In particular, we show that for deficit angle branes the brane energy momentum tenso…
