The Graviton Propagator in Asymptotically Safe Gravity with Non-Local Form Factors
Emiliano Maria Glaviano
We analyze the flow of the background graviton propagator driven by the running of asymptotically safe form factors in four-dimensional quantum gravity at quadratic order in the cu…
Asymptotically Safe Gravitational Form Factors from the Proper-Time Flow Equation
Emiliano Maria Glaviano
We study the renormalization group flow of non-local form factors in four-dimensional quantum gravity within the proper-time formalism at quadratic order in the curvature expansion…
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…
Fifth-Force Constraints from UV-Complete Scalar-Tensor Gravity
Alfio M. Bonanno, Emiliano M. Glaviano
We study an scalar multiplet nonminimally coupled to gravity and follow its renormalization-group (RG) flow in the vicinity of an interacting, nonperturbatively UV-complete…
Scaling Solutions of Matter Form Factors in Asymptotically Safe Quantum Gravity
Alfio M. Bonanno, Diego Buccio, Emiliano M. Glaviano +1
We investigate the renormalization group flow of a gravity--matter system in which a scalar field is minimally coupled to Einstein gravity and its kinetic term is given by a scale-…
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…
