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…
