Dirac field, van der Waals gas, Weyssenhoff fluid, Newton particle
Luca Fabbri
We consider the Dirac field in polar formulation, showing that when torsion is taken in effective approximation the theory has the thermodynamic properties of a van der Waals gas,…
Madelung Structure of the Dirac Equation
Luca Fabbri
We consider the Dirac equations in polar form proving that they can equivalently be re-configured into a system of equations consisting of derivatives of the velocity density plus…
Unraveling the Physical Meaning Behind Elko's Dual structure
Gabriel Brandão de Gracia, Rodolfo José Bueno Rogerio, Luca Fabbri
In this work, we shall analyze the necessity of a proper definition of the dual structure for Elko spinors, and singular spinors in general. We examine in detail why the Dirac dual…
Classical characters of spinor fields in torsion gravity
Luca Fabbri
We consider the problem of having relativistic quantum mechanics re-formulated with hydrodynamic variables, and specifically the problem of deriving the Mathisson-Papapetrou-Dixon…
Geometry of spinors: doubly-chiral plane-wave expansion
Luca Fabbri
We employ the polar re-formulation of spinor fields to see in a new light their classification into regular and singular spinors, these last also called flag-dipoles, further split…
