幻影场与修正的Chaubergin气体的相互作用

Interaction between phantom field and modified Chaplygin gas

Surajit Chattopadhyay, Ujjal Debnath

摘要:

在这封信中,我们考虑了平坦的FRW宇宙。代替只考虑暗能量的一个候选者,我们考虑了幻影场和修改的Chaubergin气体之间的相互作用。已经表明,随着宇宙的演化,幻影场的电势从较低的值增加。我们观察到,随着宇宙时间的推移,电场有增大的趋势,电势也有增大的趋势。在宇宙演化过程中,这种相互作用模型实现了$w=-1$的跨越。

英文摘要:

In this letter, we have considered a flat FRW universe. Instead of considering only one candidate for dark energy, we have considered interaction between phantom field and modified Chaplygin gas. It has been shown that the potential of the phantom field increases from a lower value with evolution of the Universe. It has been observed that, the field has an increasing tendency and potential has also an increasing tendency with passage of cosmic time. In the evolution of the universe the crossing of $w=-1$ has been realized by this interacting model.
