Abstract
We investigate the relativistic quantum dynamics of the spinless particles in a Robertson-Walker spacetime (RWS) in the framework of gravity’s rainbow (RG) when homogeneous electromagnetic fields exist. Exact solutions of the Klein-Gordon equation (KGE) are obtained and the amount of the created pairs is calculated by employing the Bogoliubov transformation method (BTM). The effects of homogeneous electromagnetic fields interacting with gravitational fields on particle production rate are discussed.
