英文摘要The dynamics of the interacting dark energy model in loop quantum cosmology (LQC) is studied in this paper. The dark energy has a constant equation of state wx and interacts with dark matter through a form 3cH(rho(x) + rho(m)). We find that for the quintessence model (w(x) > -1) the cosmological evolution in LQC is the same as that in classical Einstein cosmology, whereas for phantom dark energy (w(x) < -1), although there are the same critical points in LQC and classical Einstein cosmology, the loop quantum effect significantly reduces the parameter spacetime (c, w(x)) required by stability. If parameters c and wx satisfy the conditions that the critical points are existing and stable, the universe will enter an era dominated by dark energy and dark matter with a constant energy ratio between them, and accelerate forever; otherwise it will enter an oscillatory regime. Comparing our results with the observations we find at 1 sigma confidence level that the universe will accelerate forever.
