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…

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…
