一个新的变量修正Chaubergin气体模型与标量场相互作用

A New Variable Modified Chaplygin Gas Model Interacting with Scalar Field

Writambhara Chakraborty, Ujjal Debnath

摘要:

在这封信中,我们提出了一个新的形式的著名Chaubergin气体模型通过引入不均匀性的状态方程。该模型解释了$ω=-1$交叉。此外,我们给出了一个图形表示的模型使用$\{r,s\}$参数。通过引入唯象耦合函数,我们还考虑了该模型与标量场的相互作用,并证明了势随时间衰减。

英文摘要:

In this letter we present a new form of the well known Chaplygin gas model by introducing inhomogeneity in the EOS. This model explains $ω=-1$ crossing. Also we have given a graphical representation of the model using $\{r,s\}$ parameters. We have also considered an interaction of this model with the scalar field by introducing a phenomenological coupling function and have shown that the potential decays with time.
