Coulomb scattering for scalar field in Scr\" odinger picture
Crucean Cosmin, Racoceanu Radu, Pop Adrian
The scattering of a charged scalar field on Coulomb potential on de Sitter space-time is studied using the solution of the free Klein-Gordon equation. We find that the scattering a…
Dirac-Coulomb scattering with plane wave energy eigenspinors on de Sitter expanding universe
Ion I. Cotaescu, Crucean Cosmin
The lowest order contribution of the amplitude of Dirac-Coulomb scattering in de Sitter spacetime is calculated assuming that the initial and final states of the Dirac field are de…
Reduction formalism for Dirac fermions on de Sitter spacetime
Cosmin Crucean, Radu Racoceanu
The reduction formulas for Dirac fermions are derived, using the exact solutions of free Dirac equation on de Sitter spacetime. In the framework of the perturbation theory one stud…
Infinite loop superalgebras of the Dirac theory on the Euclidean Taub-NUT space
Ion I. Cotaescu, Mihai Visinescu
The Dirac theory in the Euclidean Taub-NUT space gives rise to a large collection of conserved operators associated to genuine or hidden symmetries. They are involved in interestin…
Coulomb scattering of the Dirac field on de Sitter expanding universe
Cosmin Crucean
The lowest order contribution of the amplitude of the Dirac-Coulomb scattering in de Sitter spacetime is calculated assuming that the initial and final states of the Dirac field ar…
