Abstract
We study the behaviour of Dirac current in expanding spacetime with Schr{\"o}dinger and de Sitter form for the evolution of the scale-factor. The study is made to understand the particle-antiparticle rotation and the evolution of quantum vacuum leading to particle production in such spacetime.
