论文摘要
在本文中，我们检查了（LRS）Bianchi-Type-I宇宙学模型，具有全息暗能量。通过使用广义杂交膨胀法（HEL）获得相应场方程的确切解决方案。 DE的EOS参数$ω$被发现是时间依赖性和红移依赖性，其派生模型的退出范围与当前的观测值一致。在这里，我们同样应用两个数学诊断，即StateFinder（{r，s}）和$ω__{d}-omΩ^{'} _ {d} $ plane将HDE模型从$λcdm$模型中隔离。在这里，$ω__{d}-Ω^{'} _ {d} $诊断轨迹是对动态DE模型进行分类的好工具。我们发现我们的模型在解冻区域和冻结区域。我们还构建了典型和tachyon标量场的潜力和动力学。该模型的某些物理和几何特性以及宇宙学解决方案的物理可接受性已详细讨论。
In this paper, we examine the (LRS) Bianchi-type-I cosmological model with holographic dark energy. The exact solutions to the corresponding field equations are obtained by using generalized hybrid expansion law (HEL). The EoS parameter $ω$ for DE is found to be time dependent and redshift dependent and its exiting range for derived model is agreeing well with the current observations. Here we likewise apply two mathematical diagnostics, the statefinder ({r, s}) and $ω_{d}-ω^{'}_{d}$ plane to segregate HDE model from the $ΛCDM$ model. Here the $ω_{d}-ω^{'}_{d}$ diagnostic trajectories is the good tool to classifying the dynamical DE model. We found that our model lies in both thawing region and freezing region. We have also construct the potential as well as dynamics of the quintessence and tachyon scalar field. Some physical and geometric properties of this model along with the physical acceptability of cosmological solution have been discussed in detail.
