f(T)宇宙学中的吸引子解

Attractor Solutions in f(T) Cosmology

Mubasher Jamil, D. Momeni, Ratbay Myrzakulov

摘要:

本文研究了基于挠率引力的相互作用暗能量模型$f(T)$的宇宙学意义。假设暗能量与暗物质和辐射成分相互作用,我们通过选择不同形式的相互作用项来考察这个模型的稳定性。我们考虑了三种不同形式的暗能量:宇宙学常数,精粹和幻影能量。然后,我们得到几个吸引子的解决方案,每个暗能量模型与其他组件的相互作用。这个模型通过相互作用的暗能量方案成功地解释了符合问题。

英文摘要:

In this paper, we explore the cosmological implications of interacting dark energy model in a torsion based gravity namely $f(T)$. Assuming dark energy interacts with dark matter and radiation components, we examine the stability of this model by choosing different forms of interaction terms. We consider three different forms of dark energy: cosmological constant, quintessence and phantom energy. We then obtain several attractor solutions for each dark energy model interacting with other components. This model successfully explains the coincidence problem via the interacting dark energy scenario.
