论文摘要
在这项工作中，我们讨论了在巴罗最近提出的在巴罗全息暗能量（Indrared cutoff）的情况下，在Barrow Holotraphic Dark Energy（红外临界值）的存在下是Barrow最近提出的Hubble's Horizon（物理字母B 808（2020）：135643），$ f（Q）$ f（Q）$ f（q）对于$ f（q）=λq^{2} $的特定选择（其中$λ<0 $是常数）。为了找到对字段方程的确切解决方案，我们认为减速参数$ q $是哈勃参数$ h $的函数，即$ q = b- \ frac {n} {h} $（其中$ b $ and $ n $是常量）。我们研究了重要的宇宙学参数的身体行为，例如EOS参数，BHDE和物质密度，偏度参数，平方声速度和$ω__{B} {B}-omΩ__{b}^{^{^{^{\ prime}} $平面。此外，我们使用$ 57 Hubble的参数测量来限制模型参数$ b $和$ n $的值。
In this work, we have discussed a spatially homogeneous and anisotropic Bianchi type-I space-time in the presence of Barrow holographic dark energy (infrared cut-off is the Hubble's horizon) proposed by Barrow recently (Physics Letters B 808 (2020): 135643) and matter in the framework of $f(Q)$ gravity where the non-metricity $Q$ is responsible for the gravitational interaction for the specific choice of $f(Q)=λQ^{2}$ (where $λ<0$ is a constant). To find the exact solutions to the field equations we consider the deceleration parameter $q$ is a function of the Hubble's parameter $H$ i.e. $q=b-\frac{n}{H}$ (where $b$ and $n$ are constants). We have studied the physical behavior of important cosmological parameters such as the EoS parameter, BHDE and matter density, skewness parameter, squared sound speed, and $ω_{B}-ω_{B}^{^{\prime }}$ plane. Also, we constrain the values of the model parameters $b$ and $n$ using $57$ Hubble's parameter measurements.
