从全息原理看零宇宙学常数与非零暗能量

Zero Cosmological Constant and Nonzero Dark Energy from Holographic Principle

Jae-Weon Lee

摘要:

结果表明,热力学第一定律和全息原理应用于任意大的宇宙因果视界,必然要求宇宙学常数为零,动力学暗能量以全息暗能量的形式存在。半经典分析表明,全息暗能量有一个参数$d=1$和一个状态方程与目前的观测数据,如果视界的熵饱和的贝肯斯坦-霍金界限。这一结果表明,量子场论应该在大尺度上进行修正,以解释暗能量。讨论了暗能量、量子真空能和熵引力之间的关系。

英文摘要:

It is shown that the first law of thermodynamics and the holographic principle applied to an arbitrary large cosmic causal horizon naturally demand the zero cosmological constant and non-zero dynamical dark energy in the form of the holographic dark energy. Semiclassical analysis shows that the holographic dark energy has a parameter $d=1$ and an equation of state comparable to current observational data, if the entropy of the horizon saturates the Bekenstein-Hawking bound. This result indicates that quantum field theory should be modified at large scale to explain dark energy. The relations among dark energy, quantum vacuum energy and entropic gravity are also discussed.
