4. Non-existence of rest-frame spin-eigenstate spinors in their own electrodynamics / Fabbri, Luca ; da Rocha, Roldão
We assume a physical situation where gravity with torsion is neglected for an electrodynamically self-interacting spinor that will be taken in its rest-frame and spin-eigenstate: we demonstrate that under this circumstance no solution exists for the system of field equations. [...]

5. Unveiling a spinor field classification with non-Abelian gauge symmetries / Fabbri, Luca ; da Rocha, Roldão
A spinor fields classification with non-Abelian gauge symmetries is introduced, generalizing the U(1) gauge symmetries-based Lounesto's classification. [...]

6. Torsion axial vector and Yvon-Takabayashi angle: zitterbewegung, chirality and all that / Fabbri, Luca ; da Rocha, Roldão
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 interesting relationships of the torsion axial vector and the curvature tensor with the Yvon-Takabayashi angle and the module of the spinor field, that is the two degrees of freedom of the spinor field itself: in particular, we shall discuss in what way the torsion axial vector could be seen as the potential of a specific interaction of the Yvon-Takabayashi angle, and therefore as a force between the two chiral projections of the spinor field itself.
