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.

改良罗伯逊-沃克宇宙中电磁场的成对作用
我们在重力虹(RG)框架内研究了存在同质电磁场时罗伯逊-沃克时空(RWS)中无自旋粒子的相对论量子动力学。研究获得了克莱因-戈登方程(KGE)的精确解,并利用波哥留布夫变换方法(BTM)计算了所产生的粒子对的数量。讨论了同质电磁场与引力场相互作用对粒子生成率的影响。
