Scattering of Dirac fermions by spherical massive bodies
Ion I. Cotaescu, Ciprian A. Sporea
The asymptotic form of Dirac spinors in the field of a Schwarzschild black hole is used for deriving analytically for the first time the phase shifts of the partial wave analysis o…
Integral representation of the Feynman propagators of the Dirac fermions on the de Sitter expanding universe
Ion I. Cotaescu
The propagators of the Dirac fermions on the expanding portion of the (1+3)-dimensional de Sitter spacetime are considered as mode sums in momentum representation with a fixed vacu…
Propagators of the Dirac fermions on spatially flat FLRW spacetimes
Ion I. Cotaescu
The general formalism of the free Dirac fermions on spatially flat -dimensional Friedmann-Lema\^ itre-Robertson-Walker (FLRW) spacetimes is developed in momentum representat…
Propagators of the Dirac fermions in de Sitter expanding universe
Ion I. Cotaescu
The propagators of the Dirac fermions are studied in the configuration representation on the expanding portion of the -dimensional de Sitter spacetime considering a fixed va…
Collective classical motion on hyperbolic spacetimes of any dimensions
Ion I. Cotaescu
The geodesics equations on de Sitter and anti-de Sitter spacetimes of any dimensions, are the starting point for deriving the general form of the Boltzmann equation in terms of con…
