Abstract

In this work , new agegraphic dark energy in the cyclic universe has investigated. Our main goal is considering this model in the high energy regime. Since, cyclic universe is explained by a phantom phase (w < -1), it is shown when there is no interaction between matter and dark energy, new agegraphic dark energy can not produce a phantom phase, so it can not describe cyclic universe. Therefore, we study interacting models of new agegraphic dark energy. We find out that, in the high energy regime, which it is a necessary part of cyclic universe evolution, agegraphic dark energy can not create a phantom phase, but in special case, new agegraphic dark energy can describe this phantom phase era for cyclic universe.
