In this work, we propose a non-interacting model of Barrow holographic dark energy (BHDE) using Barrow entropy in a spatially flat FLRW Universe considering the IR cutoff as the Hubble horizon. We study the evolutionary history of important cosmological parameters, in particular, deceleration parameter, equation of state (EoS) parameter, the BHDE and matter density parameter, and also observe satisfactory behaviors in the BHDE model. The stability of the BHDE model has been examined by squared sound speed [Formula: see text]. In addition, to describe the accelerated expansion of the Universe, the correspondence of the BHDE model with the quintessence scalar field has been reconstructed.

以哈勃视界为红外截止的巴罗全息暗能量

在这项工作中，我们提出了一个非相互作用的巴罗全息暗能量 (BHDE) 模型，该模型使用空间平坦 FLRW 宇宙中的巴罗熵，将红外截止点视为哈勃视界。我们研究了重要的宇宙学参数的演化历史，特别是减速参数、状态方程 (EoS) 参数、BHDE 和物质密度参数，并在 BHDE 模型中观察到了令人满意的行为。BHDE 模型的稳定性已通过平方声速 [公式：见正文] 进行了检验。此外，为了描述宇宙的加速膨胀，重构了 BHDE 模型与典型标量场的对应关系。
