混合经典暴胀

Hybrid Quintessential Inflation

Mar Bastero-Gil, Arjun Berera, Brendan M. Jackson, Andy Taylor

摘要:

提出了一个模型,其中一个单一的标量场是负责既在早期的原始暴胀,然后在后期的暗能量。这个场耦合到第二个标量场,该场在原始膨胀之后变得不稳定并开始振荡,从而驱动可以产生高的膨胀后温度的再加热阶段。这个模型很容易避免产生过多的重力波,这是一个问题,在原来的经典暴胀模型中,再加热发生通过引力粒子的生产。

英文摘要:

A model is presented in which a single scalar field is responsible for both primordial inflation at early times and then dark energy at late times. This field is coupled to a second scalar field which becomes unstable and starts to oscillate after primordial inflation, thus driving a reheating phase that can create a high post-inflation temperature. This model easily avoids overproduction of gravity waves, which is a problem in the original quintessential inflation model in which reheating occurs via gravitational particle production.
