ELKO, flagpole and flag-dipole spinor fields, and the instanton Hopf fibration
Roldao da Rocha, J. M. Hoff da Silva
In a previous paper we explicitly constructed a mapping that leads Dirac spinor fields to the dual-helicity eigenspinors of the charge conjugation operator (ELKO spinor fields). EL…
Pair and Impar, Even and Odd Form Fields and Electromagnetism
Roldao da Rocha, Waldyr A. Rodrigues
In this paper after reviewing the Schouten and de Rham definition of impair and pair differential form fields (not to be confused with differential form fields of even and odd grad…
Gauge Fixing in the Maxwell Like Gravitational Theory in Minkowski Spacetime and in the Equivalent Lorentzian Spacetime
Roldao da Rocha, Waldyr A. Rodrigues
In a previous paper we investigate a Lagrangian field theory for the gravitational field (which is there represented by a section g^a of the orthonormal coframe bundle over Minkows…
k-deformed Poincare algebras and quantum Clifford-Hopf algebras
Roldao da Rocha, Alex E. Bernardini, Jayme Vaz
The Minkowski spacetime quantum Clifford algebra structure associated with the conformal group and the Clifford-Hopf alternative k-deformed quantum Poincare algebra is investigated…
