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…
Regular Black Holes from Proper-Time flow in Quantum Gravity and their Quasinormal modes, Shadow and Hawking radiation
Alfio Bonanno, Roman A. Konoplya, Giovanni Oglialoro +1
We derive a class of regular black holes from the proper-time renormalization group approach to asymptotically safe gravity. A central challenge is the robustness of physical predi…
Gauge and parametrization dependence of Quantum Einstein Gravity within the Proper Time flow
Alfio Bonanno, Giovanni Oglialoro, Dario Zappalà
Proper time functional flow equations have garnered significant attention in recent years, as they are particularly suitable in analyzing non-perturbative contexts. By resorting to…
