Volume elements and torsion
Ricardo A. Mosna, Alberto Saa
We reexamine here the issue of consistency of minimal action formulation with the minimal coupling procedure (MCP) in spaces with torsion. In Riemann-Cartan spaces, it is known tha…
Quantum-classical correspondence via a deformed kinetic operator
Ricardo A. Mosna, Ian P. Hamilton, Luigi Delle Site
We propose an approach to the quantum-classical correspondence based on a deformation of the momentum and kinetic operators of quantum mechanics. Making use of the factorization me…
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)…
