Polar Form of the Dirac Operator in Low-Dimensional Space-Times
Luca Fabbri, Giuseppe De Maria
The paper rewrites the Dirac operator in a polar form as left‑multiplication by a specific matrix and uses this representation to compute its right‑resolvent in low‑dimensional spa…

Spin-dependent neutrino oscillations in torsion backgrounds: A quantum-field-theoretic analysis
Raoul Serao, Giuseppe De Maria, Simone Monda +2
We study neutrino mixing in a background with spacetime torsion within the quantum-field-theoretic formulation of flavor oscillations. Working in the Einstein--Cartan framework and…
