Gravitationally Induced UV Completion of an Scalar Theory
Alfio M. Bonanno, Emiliano M. Glaviano
We investigate the ultraviolet completion of an scalar field theory non-minimally coupled to gravity using the Wilsonian functional renormalization group in the proper-time…
Proper-time functional renormalization in scalar models coupled to gravity
Alfio M. Bonanno, Emiliano M. Glaviano, Gian Paolo Vacca
We focus on the use of the functional Wilsonian renormalization group framework characterized by a proper time regulator and test its use in the search of the scaling solutions and…
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…
Searching for quantum-gravity footprint around stellar-mass black holes
Luigi Foschini, Alberto Vecchiato, Alfio Bonanno
According to the asymptotically safe gravity, black holes may have characteristics different from those described according to general relativity if the running of the gravitationa…
RG studies of scalar-field models of long-range interactions
Alfio M. Bonanno, S. R. Haridev, Gaurav Narain
In this work we studies the long-range interactions in non-gravitational field theories and their behaviour in the deep infrared. To model such effects, we consider a nonlocal scal…
Veiled Singularities in Einstein-Weyl Gravity: Stability and Physical Interpretation of Horizonless Solutions
Alfio M. Bonanno, Samuele Silveravalle, Andrea Spina
We investigate a class of horizonless solutions in Einstein-Weyl gravity, corresponding to the so-called attractive naked singularities of the (-2,2) type. In contrast to General R…
