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…
The Graf product: a Clifford structure framework on the exterior bundle
R. Lopes, R. da Rocha
The geometric product, defined by Graf on the space of differential forms, endows the sections of the exterior bundle by a structure that is necessary to construct a Clifford algeb…
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…
Opening the Pandora's box of quantum spinor fields
L. Bonora, J. M. Hoff da Silva, R. da Rocha
Lounesto's classification of spinors is a comprehensive and exhaustive algorithm that, based on the bilinears covariants, discloses the possibility of a large variety of spinors, c…
GUP Hawking fermions from MGD black holes
Roberto Casadio, Piero Nicolini, Roldao da Rocha
We derive the Hawking spectrum of fermions emitted by a minimally geometric deformed (MGD) black hole. The MGD naturally describes quantum effects on the geometry in the form of a…
Gregory-Laflamme analysis of MGD black strings
A. Fernandes-Silva, R. da Rocha
The minimal geometric deformation (MGD), associated with the 4D Schwarzschild solution of the Einstein equations, is shown to be a solution of the pure 4D Ricci quadratic gravity t…
