Asymptotically safe gravity as a scalar-tensor theory and its cosmological implications
Asymptotically gravity scalar-tensor theory cosmological implications
2011/10/14
We study asymptotically safe gravity with Einstein-Hilbert truncation taking into account the renormalization group running of both gravitational and cosmological constants. We show the classical beha...
Ghost anomalous dimension in asymptotically safe quantum gravity
ghost anomalous dimension quantum gravity
2010/3/22
We compute the ghost anomalous dimension within the asymptotic-safety scenario for quantum gravity. For a class of covariant gauge fixings and using a functional RG scheme, the anomalous dimension $\e...
