熵宇宙学:暴胀和晚期加速的统一模型

Entropic cosmology: a unified model of inflation and late-time acceleration

Yi-Fu Cai, Jie Liu, Hong Li

摘要:

全息被认为是量子广义相对论最有前途的描述之一。我们提出了一个包含两个全息屏幕的宇宙学系统模型,发现它们的平衡态正好产生一个标准的Friedmann-Robertson-Walker宇宙。我们讨论了它的宇宙学意义,考虑到高阶量子修正和量子性质的地平线蒸发。我们将证明这个模型可以在高能尺度上产生全息暴胀,并以统一的方法实现后期加速。我们测试我们的模型从超新星Ia观测,发现它可以给一个很好的拟合的数据。

英文摘要:

Holography is expected as one of the promising descriptions of quantum general relativity. We present a model for a cosmological system involving two holographic screens and find that their equilibrium exactly yields a standard Friedmann-Robertson-Walker universe. We discuss its cosmological implications by taking into account higher order quantum corrections and quantum nature of horizon evaporation. We will show that this model could give rise to a holographic inflation at high energy scales and realize a late-time acceleration in a unified approach. We test our model from the SN Ia observations and find it can give a nice fit to the data.
