Substructures of the Weyl group and their physical applications
Riccardo Martini, Gregorio Paci, Dario Sauro +2
We study substructures of the Weyl group of conformal transformations of the metric of (pseudo)Riemannian manifolds. These substructures are identified by differential constraints…
Radiative corrections to the and invariants from torsion fluctuations on maximally symmetric spaces
Riccardo Martini, Gregorio Paci, Dario Sauro
We derive the runnings of the and operators that stem from integrating out quantum torsion fluctuations on a maximally symmetric Euclidean background, while treating the…
Covariant spin-parity decomposition of the Torsion and Path Integrals
Riccardo Martini, Gregorio Paci, Dario Sauro
We propose a functional measure over the torsion tensor. We discuss two completely equivalent choices for the Wheeler-DeWitt supermetric for this field, the first one being based o…
Composite higher derivative operators in dimensions and the spectrum of asymptotically safe gravity
Riccardo Martini, Dario Sauro, Omar Zanusso
We discuss the renormalization of Einstein-Hilbert's gravity in dimensions. We show that the application of the path-integral approach leads naturally to scheme- and gauge-…
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…
Projective transformations in metric-affine and Weylian geometries
Dario Sauro, Riccardo Martini, Omar Zanusso
We discuss generalizations of the notions of projective transformations acting on affine model of Riemann-Cartan and Riemann-Cartan-Weyl gravity which preserve the projective struc…
Revisiting Common Envelope Evolution -- A New Semi-Analytic Model for N-body and Population Synthesis Codes
Alessandro Alberto Trani, Steven Rieder, Ataru Tanikawa +5
We present a novel way of modeling common envelope evolution in binary and few-body systems. We consider the common envelope inspiral as driven by a drag force with a power-law dep…
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…
Functional Renormalisation Group analysis of Tensorial Group Field Theories on
Joseph Ben Geloun, Riccardo Martini, Daniele Oriti
Rank-d Tensorial Group Field Theories are quantum field theories defined on a group manifold , which represent a non-local generalization of standard QFT, and a candi…
Functional Renormalisation Group analysis of a Tensorial Group Field Theory on
Joseph Ben Geloun, Riccardo Martini, Daniele Oriti
We study a model of Tensorial Group Field Theory (TGFT) on from the point of view of the Functional Renormalisation Group. This is the first attempt to apply a renor…
