论文摘要
在目前的工作中，我们研究了幂律熵校正的全息暗能量（Plechde）模型，该模型具有哈勃地平线临界值。我们在红移范围内使用46个观察性哈勃数据点$ 0 \ leq z \ leq 2.36 $来确定当前的哈勃常数$ h_0 $和模型参数$ n $。它代表了宇宙从减速到加速度的相位过渡，并且过渡点为$ z_t = 0.71165 $。 我们研究模型上的观察性约束，并计算一些相关的宇宙学参数。我们通过绘制与现代观察数据兼容的结果来检查模型的有效性。还探索了该模型的物理和几何特性，并且证明它们与当前观察性哈勃数据（OHD）和最新的关节光曲线（JLA）数据集的观察结果很好。
In the present work, we investigate the power-law entropy corrected holographic dark energy (PLECHDE) model with Hubble horizon cutoff. We use 46 observational Hubble data points in the redshift range $0 \leq z \leq 2.36$ to determine the present Hubble constant $H_0$ and the model parameter $n$. It represents a phase transition of the universe from deceleration to acceleration and has the transition point at $z_t = 0.71165$. We investigate the observational constraints on the model and calculate some relevant cosmological parameters. We examine the model's validity by drawing state-finder parameters that yield the result compatible with the modern observational data. The model's physical and geometrical characteristics are also explored, and they are shown to match well with current observations of observational Hubble data (OHD) and the latest joint light curves(JLA) datasets.
