Polar form of Dirac fields: implementing symmetries via Lie derivative
Luca Fabbri, Stefano Vignolo, Roberto Cianci
We consider the Lie derivative along Killing vector fields of the Dirac relativistic spinors: by using the polar decomposition we acquire the mean to study the implementation of sy…

Integrability of Dirac equations in static spherical space-times
Roberto Cianci, Stefano Vignolo, Luca Fabbri
We consider the Dirac equations in static spherically-symmetric space-times, and we present a type of spinor field whose structure allows the separation of elevation angle and radi…
