论文摘要
典型通货膨胀是指使用单个标量场来描述通货膨胀和延迟加速的情况。这篇评论专门用于典型通货膨胀的框架，重点是形式主义的基础。使用单个标量场的通货膨胀和延迟加速度的一致统一要求最初在当前时期附近再次进行陡峭的行为和浅层。标量场对热史的不干预的要求决定了通货年后时代潜力的陡峭性质，并进一步限制了较晚的物理学独立于初始条件。我们详细描述了缩放和渐近缩放解决方案以及从缩放机制到较晚加速的机理。评论包括对缩放解决方案的全面查看，这是通货膨胀统一和迟到加速的主题核心。至于退出机制，特别注意大规模中微子物质与标量场的耦合，标量磁场会动态地构建并可能引起较晚的加速。在耦合存在下，我们提出了标量场动力学的详细分析处理。我们简要讨论了典型膨胀的杰出特征，即从通货膨胀到动力学制度的过渡过程中产生的重力波的蓝色光谱。
Quintessential inflation refers to scenarios in which a single scalar field is used to describe inflation and late-time acceleration. This review is dedicated to the framework of quintessential inflation, with a focus on the building blocks of formalism. Consistent unification of inflation and late time acceleration using a single scalar field asks for a shallow field potential initially followed by steep behaviour thereafter and shallow again around the present epoch. The requirement of non-interference of scalar field with thermal history dictates steep nature of potential in the post-inflationary era, with a further restriction that late time physics be independent of initial conditions. We describe, in detail the scaling and asymptotic scaling solutions and the mechanism of exit from the scaling regime to late time acceleration. Review includes a fresh look at scaling solutions which are central to the theme of unification of inflation and late time acceleration. As for the exit mechanism, special attention is paid to the coupling of massive neutrino matter to the scalar field, which builds up dynamically and can give rise to late time acceleration. We present a detailed analytical treatment of scalar field dynamics in the presence of coupling. We briefly discuss the distinguished feature of quintessential inflation, namely, the blue spectrum of gravity waves produced during the transition from inflation to the kinetic regime.
