On the universality of the Carter and McLenaghan formula
Ion I Cotaescu
It is shown that the formula of the isometry generators of the spinor representation given by Carter and McLenaghan is universal in the sense that this holds for any representation…
The quantum theory of the free Maxwell field on the de Sitter expanding universe
Ion I. Cotaescu, Cosmin Crucean
The theory of the free Maxwell field in two moving frames on the de Sitter spacetime is investigated pointing out that the conserved momentum and energy operators do not commute to…
Charges and Mass Spectrum in the Pisano-Pleitez-Frampton 3-3-1 Gauge Model
Ion I. Cotaescu, Adrian Palcu
The Pisano-Pleitez-Frampton 3-3-1 model is revisited here within the framework of the general method for solving gauge models with high symmetries. This exact algebraical approach…
The quantum theory of scalar fields on the de Sitter expanding universe
Ion I. Cotaescu, Cosmin Crucean, Adrian Pop
New quantum modes of the free scalar field are derived in a special time-evolution picture that may be introduced in moving charts of de Sitter backgrounds. The wave functions of t…
