Abstract

We use the semiclassical approach to solve the Klein–Gordon and Dirac equations in the presence of a time-varying electric field. Our objective is to calculate the density of particle creation in a cosmological anisotropic Bianchi- I space–time. We demonstrate that when the electric interaction is proportional to the Ricci scalar of curved space–time, the distribution of particles subjected to the electric field transforms into a thermal state.

时变电场在宇宙时空中创造粒子

摘要我们使用半经典方法求解存在时变电场的克莱因-戈登方程和狄拉克方程。我们的目标是计算宇宙学各向异性的边沁一时空中粒子产生的密度。我们证明，当电相互作用与弯曲时空的利玛窦标量成正比时，受电场作用的粒子分布会转化为热状态。
