可解K-本质宇宙学与修正的暗能量和暗物质的Chaobergin气体统一模型
Solvable K-essence Cosmologies and Modified Chaplygin Gas Unified Models of Dark Energy and Dark Matter
摘要:
本文在可解k-本质宇宙学的背景下研究了修正的Chaubergin气体模型。为此,我们构造了该模型的状态参数方程的某些特定值的参数$n$。并利用势的幂律形式讨论了这些方程的图形性态。在暗能量的情况下,k-本质和改进的Chaobergin气体模型之间的关系显示了可行的结果。我们的结论是,宇宙行为作为一个宇宙学常数,quintessence阶段或幻影阶段取决于$n$。
英文摘要:
This paper is devoted to the investigation of modified Chaplygin gas model in the context of solvable k-essence cosmologies. For this purpose, we construct equations of state parameter of this model for some particular values of the parameter $n$. The graphical behavior of these equations are also discussed by using power law form of potential. The relationship between k-essence and modified Chaplygin gas model shows viable results in the dark energy scenario. We conclude that the universe behaves as a cosmological constant, quintessence phase or phantom phase depending upon $n$.
