Bilocal flows and universality with field-dependent regulators
Alfio M. Bonanno, Renata Ferrero
Many functional renormalization group flows employ a regulator that depends on the fields, as in proper-time and spectrally adjusted flows and in background-independent formulation…
Towards gauge independence in asymptotically safe quantum gravity
Kevin Falls, Renata Ferrero, Giovanni Oglialoro
We study gauge dependence in proper-time renormalisation group flows for asymptotically safe quantum gravity. Working in an essential scheme, we use field redefinitions to separate…
Coarse graining from within: Wilson-Fisher universality on
Alfio M. Bonanno, Renata Ferrero, Giovanni Oglialoro
Wilsonian renormalization is usually formulated in momentum space, but on curved backgrounds momentum shells have no invariant meaning. We replace them by an intrinsic spectral cut…
Asymptotic Safety and Canonical Quantum Gravity
Renata Ferrero
In the context of gravity the Lagrangian and Hamiltonian formalisms have been developed largely independently, emphasizing renormalization and quantization, respectively. The forma…
Asymptotically safe canonical quantum gravity: Gaussian dust matter
Renata Ferrero, Thomas Thiemann
In a recent series of publications we have started to investigate possible points of contact between the canonical (CQG) and the asymptotically safe (ASQG) approach to quantum grav…
Path integral measures and diffeomorphism invariance
Alfio Bonanno, Kevin Falls, Renata Ferrero
Much like the action, diffeomorphism invariance can be used to fix the form of the path integral measure in quantum gravity. Moreover, since there is a redundancy between what cons…
De Sitter quantum gravity within the covariant Lorentzian approach to asymptotic safety
Edoardo D'Angelo, Renata Ferrero, Markus B. Fröb
Recent technical and conceptual advancements in the asymptotic safety approach to quantum gravity have enabled studies of the UV completion of Lorentzian Einstein gravity, emphasiz…
Relational Lorentzian Asymptotically Safe Quantum Gravity: Showcase model
Renata Ferrero, Thomas Thiemann
In a recent contribution we identified possible points of contact between the asymptotically safe and canonical approach to quantum gravity. The idea is to start from the reduced p…
Heat kernel coefficients for massive gravity
Renata Ferrero, Markus B. Fröb, William C. C. Lima
We compute the heat kernel coefficients that are needed for the regularization and renormalization of massive gravity. Starting from the Stueckelberg action for massive gravity, we…
Universal definition of the non-conformal trace anomaly
Renata Ferrero, Sebastián A. Franchino-Viñas, Markus B. Fröb +1
We show that there exists a generalized, universal notion of the trace anomaly for theories which are not conformally invariant at the classical level. The definition is suitable f…
