Revisiting Clifford algebras and spinors II: Weyl spinors in Cl(3,0) and Cl(0,3) and the Dirac equation
Roldao da Rocha, Jayme Vaz
This paper is the second one of a series of three and it is the continuation of math-ph/0412074. We review some properties of the algebraic spinors in Cl(3,0) and Cl(0,3) and how W…
Twistors, Generalizations and Exceptional Structures
Roldao da Rocha, Jayme Vaz
This paper is intended to describe twistors via the paravector model of Clifford algebras and to relate such description to conformal maps in the Clifford algebra over R(4,1), besi…
Quantum tomography for Dirac spinors
Ricardo A. Mosna, Jayme Vaz
We present a tomographic scheme, based on spacetime symmetries, for the reconstruction of the internal degrees of freedom of a Dirac spinor. We discuss the circumstances under whic…
Z_2-gradings of Clifford algebras and multivector structures
Ricardo A. Mosna, David Miralles, Jayme Vaz
Let Cl(V,g) be the real Clifford algebra associated to the real vector space V, endowed with a nondegenerate metric g. In this paper, we study the class of Z_2-gradings of Cl(V,g)…
On the Equation rotA = K A
J. Vaz, W. A. Rodrigues
We show that when correctly formulated the equation $\nabla \times \mbox{\boldmath $a$} = κ\mbox{\boldmath $a$}$ does not exhibit some inconsistencies atributed to it, so that its…
