Perturbative approaches to non-perturbative quantum gravity
Riccardo Martini, Gian Paolo Vacca, Omar Zanusso
We discuss the birth of the non-perturbative approach to quantum gravity known as quantum Einstein gravity, in which the gravitational interactions are conjectured to be asymptotic…
Trisections in colored tensor models
Riccardo Martini, Reiko Toriumi
We give a procedure to construct (quasi-)trisection diagrams for closed (pseudo-)manifolds generated by colored tensor models without restrictions on the number of simplices in the…
The search for the universality class of metric quantum gravity
Riccardo Martini, Alessandro Ugolotti, Omar Zanusso
On the basis of a limited number of reasonable axioms, we discuss the classification of all the possible universality classes of diffeomorphisms invariant metric theories of quantu…
Gravity in dimensions and realizations of the diffeomorphisms group
Riccardo Martini, Alessandro Ugolotti, Francesco Del Porro +1
We discuss two distinct realizations of the diffeomorphism group for metric gravity, which give rise to theories that are classically equivalent, but quantum mechanically distinct.…
Renormalization of multicritical scalar models in curved space
Riccardo Martini, Omar Zanusso
We consider the leading order perturbative renormalization of the multicritical models and some generalizations in curved space. We pay particular attention to the nonmini…
A curvature bound from gravitational catalysis
Holger Gies, Riccardo Martini
We determine bounds on the curvature of local patches of spacetime from the requirement of intact long-range chiral symmetry. The bounds arise from a scale-dependent analysis of gr…
