Semiclassical Lensing and Radiative Lens Equations
Claudio Corianò, Mario Cretì, Leonardo Torcellini
We analyze lensing of photons and neutrinos in a gravitational field, proposing a method to include radiative effects in classical lens equations. The study uses Schwarzschild and…
The Gravitational Chiral Anomaly at Finite Temperature and Density
Claudio Corianò, Mario Cretì, Stefano Lionetti +1
We investigate the gravitational anomaly vertex (graviton - graviton - axial current) under conditions of finite density and temperature. Through a direct an…
Axion-like Interactions and CFT in Topological Matter, Anomaly Sum Rules and the Faraday Effect
Claudio Corianò, Mario Cretì, Stefano Lionetti +2
We discuss fundamental aspects of chiral anomaly-driven interactions in conformal field theory (CFT) in four spacetime dimensions. They find application in very general contexts, f…
Axion-like Quasiparticles and Topological States of Matter: Finite Density Corrections of the Chiral Anomaly Vertex
Claudio Corianò, Mario Cretì, Stefano Lionetti +1
We investigate the general structure of the chiral anomaly and vertices, in the presence of chemical potentials in perturbation theory. The study finds appli…
Einstein Gauss-Bonnet Gravity without a Dilaton
Claudio Corianò, Mario Cretì, Stefano Lionetti +2
A nonlocal version of Einstein-Gauss Bonnet (EGB) gravity can be generated by a procedure that follows closely the steps of the derivation of the conformal anomaly effective action…
Three-Wave and Four-Wave Interactions in the Einstein Gauss-Bonnet (EGB) and Lovelock Theories
Claudio Corianò, Mario Cretì, Stefano Lionetti +1
We derive the conformal constraints satisfied by classical vertices of a (Einstein) Gauss-Bonnet theory around flat space, in general dimensions and at (4d EGB). In EGB…
Broken Scale Invariance and the Regularization of a Conformal Sector in Gravity with Wess-Zumino actions
Claudio Corianò, Mario Cretì, Matteo Maria Maglio
We elaborate on anomaly induced actions of the Wess-Zumino (WZ) form and their relation to the renormalized effective action, which is defined by an ordinary path integral over a c…
Quantum Field Theory and its Anomalies for Topological Matter
Claudio Corianò, Mario Cretì, Stefania D'Agostino
Topology enters in quantum field theory (qft) in multiple forms: one of the most important, in non-abelian gauge theories, being in the identification of the vacuum in QCD. A v…
Dimensional Regularization of Topological Terms in Dilaton Gravity
Claudio Corianò, Mario Cretì, Stefano Lionetti +2
The possibility of evading Lovelock's theorem at , via a singular redefinition of the dimensionless coupling of the Gauss-Bonnet term, has been extensively discussed in the co…
