论文摘要
在这项工作中，我们研究了早期宇宙中巴罗全息暗能（BHDE）驱动的通货膨胀机制。 BHDE基于地平线熵的巴罗关系，这反过来又从Covid-19病毒的形状中启发出来。巴罗（Barrow）表明，量子引力效应可能会促进黑洞结构中的复杂分形特征。由于预计通货膨胀期间的长度尺度很小，因此从早期宇宙中全息原理的应用获得的能量密度将足够大以支持通货膨胀情况。使用Granda-Oliveros IR截止日期，我们研究了充满BHDE的宇宙的通货膨胀情况。发现该模型的各种分析解，包括慢速参数，标量光谱指数和张量表比率。由于通货膨胀通常归因于标量场的存在，因此我们探索了BHDE和标量场模型之间的对应关系。为此，都考虑了典型的标量场和速度标量标量场。绘制了从田地产生的电势的演变，并发现与观测值一致。从工作中我们可以看到，BHDE可以成为黑暗能源的模型，可以成功推动早期通货膨胀。
In this work we have investigated the inflation mechanism driven by the Barrow Holographic dark energy (BHDE) in the early universe. BHDE is based on the Barrow relation for horizon entropy, which in turn is inspired from the shape of the COVID-19 virus. It was shown by Barrow that the quantum gravitational effects may instigate complex fractal features in the structure of a black hole. Since the length scale during the inflation is expected to be small, the energy density obtained from the application of the holographic principle in the early universe will be large enough to support the inflationary scenario. Using the Granda-Oliveros IR cut-off we have studied the inflationary scenario with the universe filled with BHDE. Various analytic solutions for the model were found out including the slow-roll parameters, scalar spectral index and tensor-to-scalar ratio. Since inflation is generally attributed to the presence of scalar fields, we have explored a correspondence between BHDE and scalar field models. Both canonical scalar field and the Tachyonic scalar field have been considered for this purpose. The evolution of the potential generated from the fields are plotted and found to be consistent with the observations. From the work we see that BHDE can be a model of dark energy that can successfully drive the early time inflation.
