量子宇宙模型和热力学

Quantum cosmic models and thermodynamics

Pedro F. González-Díaz, Alberto Rozas-Fernández

摘要:

当前宇宙演化的加速阶段是通过构建最经济的宇宙模型来考虑的,这些模型只使用广义相对论和一些与量子物理概率描述相关的主导量子效应。两个这样的模型进行了明确的分析。它们基于亚量子势的存在,对应于de Sitter空间的空间平坦指数模型的推广。这两个宇宙的解决方案的热力学讨论,使用第二原理作为指导,选择两者中的哪一个是更可行的。本文还讨论了模型所基于的相对论物理,它们的全息描述,经典能量条件的一些含义,以及用宇宙纠缠能量来解释暗能量。

英文摘要:

The current accelerating phase of the evolution of the universe is considered by constructing most economical cosmic models that use just general relativity and some dominating quantum effects associated with the probabilistic description of quantum physics. Two of such models are explicitly analyzed. They are based on the existence of a sub-quantum potential and correspond to a generalization of the spatially flat exponential model of de Sitter space. The thermodynamics of these two cosmic solutions is discussed, using the second principle as a guide to choose which among the two is more feasible. The paper also discusses the relativistic physics on which the models are based, their holographic description, some implications from the classical energy conditions, and an interpretation of dark energy in terms of the entangled energy of the universe.
