A functional renormalization group equation for foliated spacetimes
Stefan Rechenberger, Frank Saueressig
We derive an exact functional renormalization group equation for the projectable version of Hořava-Lifshitz gravity. The flow equation encodes the gravitational degrees of freedom…

The R^2 phase-diagram of QEG and its spectral dimension
Stefan Rechenberger, Frank Saueressig
Within the gravitational asymptotic safety program, the RG flow of the R^2 truncation in three and four spacetime dimensions is analyzed in detail. In particular, we construct RG t…
