英文摘要	Recently, it has been noticed that the amplification of the amplitude of curvature perturbation cycle by cycle can lead to a cyclic multiverse scenario, in which the number of universes increases cycle by cycle. however, this amplification will also inevitably induce either the ultimate end of corresponding cycle, or the resulting spectrum of perturbations inside corresponding universe is not scale invariant, which baffles the existence of observable universes. in this letter, we propose a design of a cyclic multiverse, in which the observable universe can emerges naturally. the significance of a long period of dark energy before the turnaround of each cycle for this implementing is shown.
