全息均分与熵最大化

Holographic equipartition and the maximization of entropy

Krishna P B, Titus K Mathew

摘要:

宇宙的加速膨胀可以解释为满足全息均分的趋势。它可以用一个简单的定律来表示,$ΔV = Δt\left(N_{surf}-εN_{bulk}\right),$其中$V$是普朗克单位的哈勃体积,$t$是宇宙时间普朗克单位,$N_{surf/bulk}$是宇宙视界/体积上的自由度。我们表明,这种全息均分定律有效地意味着熵的最大化。在宇宙学的背景下,一个遵守全息均分定律的系统表现为一个普通的宏观系统,它会进入最大熵的平衡态。我们考虑了宇宙的标准$Λ$ CDM模型,并证明了它与全息均分定律是一致的。通过分析熵的演化过程,我们发现它也会向最大熵的平衡态发展。

英文摘要:

\begin{abstract} The accelerated expansion of the universe can be interpreted as a tendency to satisfy the holographic equipartition. It can be expressed by a simple law, $ΔV = Δt\left(N_{surf}-εN_{bulk}\right),$ where $V$ is the Hubble volume in Plank units, $t$ is the cosmic time plank units and $N_{surf/bulk}$ is the degrees of freedom on the horizon/bulk of the universe. We show that this holographic equipartition law effectively implies the maximization of entropy. In the cosmological context, a system that obeys the holographic equipartition law behaves as an ordinary macroscopic system that proceeds to an equilibrium state of maximum entropy. We consider the standard $Λ$CDM model of the universe and have shown that it is consistent with the holographic equipartition law. Analyzing the entropy evolution we find that it also proceeds to an equilibrium state of maximum entropy.
