AI 中文摘要
我们在f(Q,T)引力框架下提出了一个重构的宇宙学模型，该模型能够统一描述宇宙的早期和晚期演化。该模型呈现出非奇异的非对称反弹，将初始的收缩阶段平滑地连接到随后的膨胀宇宙，并自然演化到晚期的暗能量主导时期。我们的研究聚焦于哈勃参数、能量密度、压强以及该参数的变化过程，旨在明确宇宙演化的各个阶段并探究暗能量的特性。能量条件分析显示，实现非奇异反弹所需的必要条件被违反。总体而言，重构后的f(Q,T)引力模型可有效捕捉反弹前后的宇宙动力学，提供了一个连贯的理论框架，可靠地解释了宇宙早期和晚期的演化过程。
英文摘要
We propose a reconstructed cosmological model in the framework of $f(Q,T)$ gravity, that provides a unified description of the early- and late-time evolution of the Universe. The model exhibits a non-singular asymmetric bounce, smoothly connecting an initial contracting phase to the subsequent expanding Universe and naturally evolving into a late-time dark energy-dominated epoch. Our study focuses on the progression of the Hubble parameter, energy density, pressure, and the parameter. This analysis aims to define the various stages of cosmic evolution and explore the characteristics of dark energy. The analysis of energy conditions reveals that the essential conditions for achieving a non-singular bounce are violated. Overall, the $f(Q, T)$ gravity model, once reconstructed, effectively captures the cosmic dynamics surrounding the bounce. It offers a cohesive theoretical framework that reliably explains the Universe's evolution during both its early and late stages.
