| Abstract: | Dynamics of universe can be described by Einstein’s field equations.FLRW metric is one of the solutions of Einstein’s field equations. In This work, I studied evolution equation of universe in flat geometry, observational evidences of dark energy. And Scalar field model of Dark Energy which can be the candidates of Dark energy. I mainly focused on Quintessence model; it’s phase plain analysis and parameterization of quintessence model to understand the cosmic dynamic of the universe. Quintessence is canonical scalar field which is introduced to explain late- time cosmic acceleration. The evolution of Dark Energy equation of state depends on the field potential and its properties :tracking and thawing. |
