修正的Chaubergin气体与可解F-本质宇宙学
Modified Chaplygin Gas and Solvable F-essence Cosmologies
摘要：
修正的Chaubergin气体模型（MCG）属于暗能量和暗物质的统一模型。在本文中，我们模拟MCG的框架下的f-本质宇宙学。通过构造MCG和f-本质之间的方程，求解该方程，可以得到MCG的压强和能量密度的显式表达式。作为特殊情况，我们得到了适当选择的自由参数的正压和负压的解决方案。我们还计算了描述幻影穿越的状态参数。
英文摘要：
The Modified Chaplygin Gas (MCG) model belongs to the class of a unified models of dark energy and dark matter. In this paper, we have modeled MCG in the framework of f-essence cosmology. By constructing an equation connecting the MCG and the f-essence, we solve it to obtain explicitly the pressure and energy density of MCG. As special cases, we obtain both positive and negative pressure solutions for suitable choices of free parameters. We also calculate the state parameter which describes the phantom crossing.
