Torsion Axial Vector and Yvon-Takabayashi Angle: Zitterbewegung, Chirality and all that
Luca Fabbri, Roldao da Rocha
We consider propagating torsion as a completion of gravitation in order to describe the dynamics of curved-twisted space-times filled with Dirac spinorial fields; we discuss intere…
Unveiling a spinor field classification with non-Abelian gauge symmetries
Luca Fabbri, Roldao da Rocha
A spinor fields classification with non-Abelian gauge symmetries is introduced, generalizing the the U(1) gauge symmetries-based Lounesto's classification. Here, a more general cla…
Spinor Fields, Singular Structures, Charge Conjugation, ELKO and Neutrino Masses
Luca Fabbri
In this paper, we consider the most general treatment of spinor fields, their kinematic classification and the ensuing dynamic polar reduction, for both classes of regular and sing…
General Dynamics of Spinors
Luca Fabbri
In this paper, we consider a general twisted-curved space-time hosting Dirac spinors and we take into account the Lorentz covariant polar decomposition of the Dirac spinor field: t…
A geometrical assessment of spinorial energy conditions
Luca Fabbri
We consider the problem of energy for spinor fields coupled to their surrounding curved-twisted space-time, and we show that when treated geometrically we cannot even be certain th…
Singularity-free spinors in gravity with propagating torsion
Luca Fabbri
We consider the most general renormalizable theory of propagating torsion in Einstein gravity for the Dirac matter distribution and we demonstrate that in this case torsion is a ma…
