Conserved spin operator of Dirac's theory in spatially flat FLRW spacetimes
Ion I. Cotaescu
New conserved spin and orbital angular momentum operators of Dirac's theory on spatially flat FLRW spacetimes are proposed generalizing thus recent results concerning the role of P…

Operators of quantum theory of Dirac's free field
Ion I. Cotaescu
The Pryce (e) spin and position operators of the quantum theory of Dirac's free field were re-defined and studied recently with the help of a new spin symmetry and suitable spectra…

Discrete symmetries of Dirac's theory in the de Sitter manifold
Ion I. Cotaescu, Ion Cotaescu
The discrete symmetries of the Dirac field on the de Sitter manifold are studied taking into account that this has two portions that can play the role of physical space-times, name…
