A model of dark matter dark energy interaction with some cosmic consequences (2311.13607v1)

Abstract: 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 $\rho$, pressure $p$, equation of state parameter $\omega$, and density parameter $\Omega$, we have performed energy conditions, scalar field description, and refined swampland conjecture to support the interaction model that we have developed.
