Perturbative approach to the problem of particle production in electric field on de Sitter universe
Cosmin Crucean, Mihaela-Andreea Băloi
In this letter we study the problem of scalar particle production in external electric field in de Sitter geometry. The total probability is calculated using the previously obtaine…

Reply to the "Comment on Fermion production in a magnetic field in a de Sitter Universe"
Cosmin Crucean, Mihaela-Andreea Băloi
In this paper we study the problem of gauge invariance of the first order transition amplitudes in de Sitter QED in Coulomb gauge. We consider the gauge transformations which prese…
