The Equivalence Principle Revisited
R. Aldrovandi, P. B. Barros, J. G. Pereira
A precise formulation of the strong Equivalence Principle is essential to the understanding of the relationship between gravitation and quantum mechanics. The relevant aspects are…
Kerr-Newman solution as a Dirac particle
H. I. Arcos, J. G. Pereira
For m^2 < a^2 + q^2, with m, a, and q respectively the source mass, angular momentum per unit mass, and electric charge, the Kerr--Newman (KN) solution of Einstein's equation reduc…
ADDENDUM on the mass neutrino oscillation in a gravitational field
J. G. Pereira, C. M. Zhang
In the article {\it Gen. Rel. Grav.} {\bf 32}, 1633 (2000), by J. G. Pereira and C. M. Zhang, the special relativity energy-momentum tensor was used to discuss the neutrino phase-s…
Gravitation and the Local Symmetry Group of Spacetime
M. Calcada, J. G. Pereira
According to general relativity, the interaction of a matter field with gravitation requires the simultaneous introduction of a tetrad field, which is a field related to translatio…
