Summary
The problem of accelerated expansion is a critical topic in cosmology since its discovery [1]. The main cause of accelerated expansion of the universe is a unknown force so-called dark energy (DE). To explain the nature of DE many cosmologists have proposed many models and theories. Many DE theories for dynamical DE scenario have been proposed to interpret the nature of accelerating universe. Cosmological constant Λ (ΛCDM ) [2] is the simplest candidate for DE (has a constant energy and pressure with constant equation of state). This model has faced two major problems, cosmic coincidence and fine tuning [2].
