A model of dark matter–dark energy interaction with some cosmic consequences

In this study, we will look at an interacting dark energy model. In the framework of Friedmann-Robertson-Walker (FRW) space-time, we have made the hypothesis of an interacting scheme between two fields (dark matter (DM) and dark energy (DE)). The evolution of the dark energy model in the above-menti...

Zusammenfassung:In this study, we will look at an interacting dark energy model. In the framework of Friedmann-Robertson-Walker (FRW) space-time, we have made the hypothesis of an interacting scheme between two fields (dark matter (DM) and dark energy (DE)). The evolution of the dark energy model in the above-mentioned spatially and homogeneous space-time has been studied from the viewpoint of interaction between DM and DE. This interacting scenario has been established by choosing an appropriate ansatz of the scale factor a ( t ). By computing cosmological parameters (geometrical and physical) such as deceleration parameter q , energy density ρ , pressure p , equation of state parameter ω , and density parameter Ω , we have performed energy conditions, scalar field description, and refined swampland conjecture to support the interaction model that we have developed.
