论文摘要
我们提出了一个新的四参数熵函数，该功能概括了Tsallis，Rényi，Barrow，Sharma-Mittal，Kaniadakis和Loop Quantum Gravity Entopies，以适合参数的限制。因此，我们解决了与拟议的四参数熵函数相对应的早期和晚期宇宙宇宙学。结果，事实证明，来自广义熵功能的熵宇宙学可以将早期通胀统一到宇宙晚期的黑暗能源时代。在这样的统一场景中，我们发现 - （1）通货膨胀时代是通过对哈勃参数的准表达进化来描述的，哈勃参数的出口在58个e折叠数量左右，（2）通货膨胀量可观察到的数量（如光谱指数）的频谱指标，用于较晚的张力量和张力数据，并在张力范围内与张力相关，并在张力范围内与近来的数据相同，并在张力范围内与您的近似态度相似，并且是您的近来量表，并与您的张力相似，并与您的张力相关。时间宇宙学，黑暗能量EOS参数与普朗克的结果一致，因为熵参数的相同值会导致早期宇宙中可行的通胀。此外，我们表明，来自提议的熵函数的熵宇宙学等于全息宇宙学，其中各自的全息图截止是根据粒子层及其衍生物或未来的地平线及其衍生物确定的。
We propose a new four-parameter entropy function that generalizes the Tsallis, Rényi, Barrow, Sharma-Mittal, Kaniadakis and Loop Quantum Gravity entropies for suitable limits of the parameters. Consequently, we address the early and late universe cosmology corresponding to the proposed four-parameter entropy function. As a result, it turns out that the entropic cosmology from the generalized entropy function can unify the early inflation to the late dark energy era of the universe. In such a unified scenario, we find that -- (1) the inflation era is described by a quasi de-Sitter evolution of the Hubble parameter, which has an exit at around 58 e-folding number, (2) the inflationary observable quantities like the spectral index for primordial scalar perturbation and the tensor-to-scalar ratio are simultaneously compatible with the recent Planck data, and (3) regarding the late time cosmology, the dark energy EoS parameter is found to be consistent with the Planck result for the same values of the entropy parameters that lead to the viable inflation during the early universe. Furthermore, we show that the entropic cosmology from the proposed entropy function is equivalent to holographic cosmology, where the respective holographic cut-offs are determined in terms of either particle horizon and its derivative or future horizon and its derivative.
