Interacting Holographic Dark Energy, the Present Accelerated Expansion and Black Holes
arXiv:1907.12866 · doi:10.1134/S020228932003010X
Abstract
We study the evolution of the universe by assuming an integrated model, which involves interacting dark energy and holographic principle with Hubble scale as IR cutoff. First we determined the interaction rate at which matter is converting to dark energy. In the next step, we evaluated the equation of state parameter which describes the nature of dark energy. Our result predicts that the present state of the universe is dominated by quintessence type dark energy and it will become phantom dominated in near future. Again our analysis successfully addresses the problem of present accelerated expansion of the universe and softens the coincidence problem. We also found that the universe was previously undergoing a decelerated phase of expansion and transition from deceleration to acceleration would occur at a time , where is the present age of the universe. Finally, we discuss the evolution of Black Holes in this environment.
