Abstract
In this paper we propose a dark energy-dark matter interaction model in which an early dark energy phase ‎emerges. This model is unique since the usual interacting dark matter-energy models affect the late time ‎cosmology and not the early phase. Although it sounds to be a solution for Hubble tension, but CMB dataset ‎prefers , which is inconsistent with local measurements. We will discuss the reasons ‎behind these results.
