论文摘要
在这项工作中，我们研究了一般标量调节理论的通货膨胀后的预热机制。在当前情况下，我们考虑两场场景，然后获得指数和双曲线切线形式的潜力。当忽略背景场上的背部反应时，我们研究背景系统的演变。我们检查了两个模型中参数共振引起的粒子产生。我们发现，在Minkowski空间中，参数共振的阶段可以用Mathieu方程来描述。最后，我们证明了模型中的参数共振足以满足颗粒数量的指数生长。
In this work, we investigate the preheating mechanism after inflation in general scalar-tensor theories of gravity. In the present scenario, we consider two-field scenario and then derive the potential of exponential and hyperbolic tangent forms. We study the evolution of the background system when the back reaction on the background field is neglected. We examine the particle production due to parametric resonances in both models. We find that in Minkowski space the stage of parametric resonances can be described by the Mathieu equation. Finally, we demonstrate that parametric resonances in our models are sufficiently broad possible for the exponential growth of the number of particles.
