非平坦宇宙中的相互作用修正变量Chaubergin气体
Interacting Modified Variable Chaplygin Gas in Non-flat Universe
摘要:
在非平坦宇宙中,利用修正的变量Chaubergin气体描述暗能量的相互作用,提出了一个暗能量与物质的统一模型.这两个实体相互作用的非引力,这涉及到一个耦合常数。由于动力学相互作用,这个常数的变化出现,从此改变了这些量的状态方程。在此相互作用模型中,我们导出了对应于物质和暗能量的有效状态方程。此外,幻影能量的情况下,推导出所涉及的参数的约束。
英文摘要:
A unified model of dark energy and matter is presented using the modified variable Chaplygin gas for interacting dark energy in a non-flat universe. The two entities interact with each other non-gravitationally which involves a coupling constant. Due to dynamic interaction, the variation in this constant arises that henceforth changes the equations of state of these quantities. We have derived the effective equations of state corresponding to matter and dark energy in this interacting model. Moreover, the case of phantom energy is deduced by putting constraints on the parameters involved.
