摘要

在本研究中，我们讨论了在 f(Q) 引力背景下宇宙高能时代的演化。为此，在早期宇宙动力学中考虑了恒定滚动条件。在统一求解场方程之后，在恒定滚动膨胀场的框架内通过模型参数分析了早期宇宙时代。在与观测数据相容的同时，确定了宇宙在观测数据的框架内从最初的准德西特真空状态演化为五重真空。据观测，当恒滚参数在参数空间中固定不变时，就会出现这种情况。

The Two-Phases Proposal for Inflation in the Constant-Roll Field with f(Q) Gravity

In this study, we discuss the evolution of the high-energy era of the universe in the background of f(Q) gravity. For this purpose, the constant-roll condition is considered in the early universe dynamics. After the unified solution of the field equations, the early universe era is analyzed through model parameters in the framework of the constant-roll inflationary field. Along with it is compatible with the observation data, it has been determined that the universe evolved from the initial quasi-de Sitter vacuum state to a quintessence vacuum within the framework of observational data. It is observed that this occurs when the constant-roll parameter is fixed in the parameter space.

期刊介绍： International Journal of Theoretical Physics publishes original research and reviews in theoretical physics and neighboring fields. Dedicated to the unification of the latest physics research, this journal seeks to map the direction of future research by original work in traditional physics like general relativity, quantum theory with relativistic quantum field theory,as used in particle physics, and by fresh inquiry into quantum measurement theory, and other similarly fundamental areas, e.g. quantum geometry and quantum logic, etc.
