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…

CFT Correlators and CP-Violating Trace Anomalies

Claudio CorianÃ², Stefano Lionetti, Matteo Maria Maglio

We analyze the parity-odd correlators $⟨ J J O ⟩_{o dd}$ , $⟨ J J T ⟩_{o dd}$ , $⟨ T T O ⟩_{o dd}$ and $⟨ T T T ⟩_{o dd}$ in momentum space, constrain…

Nonlocal Gravity, Dark Energy and Conformal Symmetry: Testing the Hierarchies of Anomaly-Induced Actions

Claudio CorianÃ², Stefano Lionetti, Matteo Maria Maglio +1

Conformal back-reaction generates cosmological models where the trace anomaly reflects the breaking of Weyl invariance. Analyzing these actions yields a dynamic approach to dark en…

Parity-Violating CFT and the Gravitational Chiral Anomaly

Claudio CorianÃ², Stefano Lionetti, Matteo Maria Maglio

We illustrate how the Conformal Ward Identities (CWI) and the gravitational chiral anomaly completely determine the structure of the $⟨ T T J_{5} ⟩$ (graviton-graviton-chi…

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…
