Semiclassical Lensing and Radiative Lens Equations

Claudio CorianÃ², Mario CretÃ¬, 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…

Axion-like Quasiparticles and Topological States of Matter: Finite Density Corrections of the Chiral Anomaly Vertex

Claudio CorianÃ², Mario CretÃ¬, Stefano Lionetti +1

We investigate the general structure of the chiral anomaly $A V V / AAA$ and $(LLL, R R R)$ vertices, in the presence of chemical potentials in perturbation theory. The study finds appli…

The Gravitational Chiral Anomaly at Finite Temperature and Density

Claudio CorianÃ², Mario CretÃ¬, Stefano Lionetti +1

We investigate the gravitational anomaly vertex $⟨ T T J_{5} ⟩$ (graviton - graviton - axial current) under conditions of finite density and temperature. Through a direct an…
