Dirac Fields in Hydrodynamic Form and their Thermodynamic Formulation
Luca Fabbri, Stefano Vignolo, Giuseppe De Maria +1
The paper rewrites Dirac spinor fields in a polar (hydrodynamic) form using a 1+1+2 covariant split, decomposes the resulting equations, and illustrates the approach with examples…

A covariant approach to the Dirac field in LRS space-times: the case of coplanar frames
Stefano Vignolo, Giuseppe De Maria, Sante Carloni +1
We employ the polar decomposition of the Dirac field to describe it as an effective spinorial fluid. We then construct a covariant formalism for the Dirac field that avoi…

A covariant approach to the Dirac field in LRS space-times
Stefano Vignolo, Giuseppe De Maria, Luca Fabbri +1
We use the polar decomposition to describe the Dirac field in terms of an effective spinorial fluid. After reformulating all covariant equations in ``spinorial'' signature $(+ -- )…
