Fermion production in Coulomb field on de Sitter universe
Crucean Cosmin
Fermion production in an external Coulomb field on de Sitter expanding universe is studied. The amplitude and probability of pair production in an external Coulomb field are comput…

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…
