Renormalization group flow of Hořava-Lifshitz gravity at low energies
Adriano Contillo, Stefan Rechenberger, Frank Saueressig
The functional renormalization group equation for projectable Hořava-Lifshitz gravity is used to derive the non-perturbative beta functions for the Newton's constant, cosmological…
An asymptotic safety scenario for gauged chiral Higgs-Yukawa models
Holger Gies, Stefan Rechenberger, Michael M. Scherer +1
We investigate chiral Higgs-Yukawa models with a non-abelian gauged left-handed sector reminiscent to a sub-sector of the standard model. We discover a new weak-coupling fixed-poin…
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…
Higher Derivative Gravity from the Universal Renormalization Group Machine
F. Saueressig, K. Groh, S. Rechenberger +1
We study the renormalization group flow of higher derivative gravity, utilizing the functional renormalization group equation for the average action. Employing a recently proposed…
Asymptotically Safe Lorentzian Gravity
Elisa Manrique, Stefan Rechenberger, Frank Saueressig
The gravitational asymptotic safety program strives for a consistent and predictive quantum theory of gravity based on a non-trivial ultraviolet fixed point of the renormalization…
