突现宇宙中广义Ricci暗能量对变色龙场的作用
Role of generalized Ricci dark energy on Chameleon field in the emergent universe
摘要：
本文研究了涌现宇宙中的广义里奇暗能量（GRDE）和广义全息暗能量（GHDE）。导出了宇宙突现情景下GRDE的分数能量密度和减速参数。此外，在新兴的宇宙场景中的变色龙领域的GRDE的作用进行了研究。最后，研究了在GRDE存在下，Chameleon标量场$ϕ$、相应的势$V$和关联函数$f$的行为.
英文摘要：
In this paper, we have considered the generalized Ricci dark energy (GRDE) and generalized holographic dark energy (GHDE) in the scenario of emergent universe. Fractional energy density and deceleration parameters for GRDE were derived under emergent universe scenario. Also role of GRDE on the Chameleon field in the emergent universe scenario has been examined. Finally, the behaviours of the Chameleon scalar field $ϕ$, corresponding potential $V$ and associated function $f$ were investigated in presence of GRDE.
