Joss-Weinberg covariant field with mass and spin
Ion I. Cotaescu
We present the explicit theory of the Joss-Weinberg covariant field with spin which is a eight-dimensional massive covariant field transforming according to the repre…
New charged dynamical particles in spatially flat FLRW space-times
Ion I. Cotaescu
New time-dependent metric tensors with spherical symmetry satisfying the Einstein-Maxwell equations in space-times with FLRW asymptotic behaviour are derived here for the first tim…
Masses dynamics during black hole evaporation in spatially flat FLRW universes
Ion I. Cotaescu, Ion Cotaescu
The new dynamical solutions of Einstein's equations with perfect fluid in space-times with FLRW asymptotic behaviour, derived recently \cite{Cot,Cot1,Cot2}, may describe evaporatin…
Operators of Dirac's theory with mass and axial chemical potential
Ion I. Cotaescu
The Dirac equation with mass and axial chemical potential is solved analytically obtaining the mode spinors and corresponding projection operators giving the spectral representatio…
New one-parameter models of dynamical particles in spatially flat FLRW space-times
Ion I. Cotaescu
New one-parameter models of non-rotating dynamical particles are derived as isotropic solutions of Einstein's equations with perfect fluid in space-times with FLRW asymptotic behav…
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…
