摘要

目前的工作报告了受 S. Nojiri 和 S. D. Odintsov 的启发,利用高度概括的全息暗流对反弹宇宙学的研究,2017 年,《欧洲物理杂志 C》,77,第 1-8 页。主要用于晚时加速的全息暗流体被用于重构以实现宇宙学反弹。我们首先使用了最广义的 "Nojiri-Odintsov(NO)截止点 "来实现全息暗流。通过这些解,我们探索了不同宇宙学参数的演化。我们在实现宇宙反弹的背景下考察了每个重建参数的影响。接下来,我们利用对该模型的标量谱指数、张量标量比和慢速滚动特性的分析推断,研究了反弹膨胀情景。由于通货膨胀通常与标量场的存在有关,我们研究了NO广义全息暗能量与标量场模型之间的可能关系。我们绘制了标量场产生的电位随时间的演变图。最后,我们研究了反弹前和反弹后情景下的热力学GSL。

Implementation of cosmological bounce inflation with Nojiri-Odintsov generalized holographic dark fluid
The current work reports a study on bounce cosmology with a highly generalized holographic dark fluid inspired by S. Nojiri and S. D. Odintsov, 2017, European Physical Journal C, 77, pp.1-8. The holographic dark fluid that is mostly used for late-time acceleration has been implemented to reconstruct towards realisation of cosmological bounce. We first used the most generalized Nojiri-Odintsov(NO) cutoff to implement the holographic dark fluid. Accordingly, we have reconstructed this dark fluid via some solutions of scale factors. With those solutions, we have explored the evolution of different cosmological parameters. We have examined the effects of each reconstructed parameter in the context of the realization of the cosmic bounce. Next, we use the analytical inferences of the scalar spectral index, tensor-to-scalar ratio, and slow-roll characteristics of the model to study a bounce inflationary scenario. Since inflation is usually associated with the existence of scalar fields, we looked at a possible relationship between NO generalized holographic dark energy and scalar field models. Plotting the evolution of the potential that results from the scalar fields against time. Finally, we investigated the GSL of thermodynamics in the pre-and post-bounce scenarios.
