分数Action宇宙学:涌现态、对数中间态和中间态宇宙中的一些暗能量模型
Fractional Action Cosmology: Some Dark Energy Models in Emergent, Logamediate and Intermediate Scenarios of the Universe
摘要:
在分数作用量宇宙学的框架下,我们重建了标量势和标量场,即:quintessence,phantom,tachyon,k-本质,DBI-本质,Hessence,Ekson场和Yang-Mills场。为了更好地描述标量场和势场随时间的变化,我们分别在突现、对数中间和中间三种不同的宇宙膨胀情况下,给出了标度因子的表达式。
英文摘要:
In the framework of Fractional Action Cosmology, we have reconstructed the scalar potentials and scalar fields, namely, quintessence, phantom, tachyon, k-essence, DBI-essence, Hessence, dilaton field and Yang-Mills field. To get more physical picture of the variation of the scalar field and potential with time, we express scale factor in emergent, logamediate and intermediate scenarios, under which the Universe expands differently.
