Interacting New Agegraphic Dark Energy in a Cyclic Universe

Abstract The main goal of this work is investigation of NADE in the cyclic universe scenario. Since, cyclic uni-verse is explained by a phantom phase (ω < −1), it is shown when there is no interaction between matter and dark energy, ADE and NADE do not produce a phantom phase, then can not describe cyclic universe. Therefore, we study interacting models of ADE and NADE in the modified Friedmann equa-tion. We find out that, in the high energy regime, which it is a necessary part of cyclic universe evolution, only NADE can describe this phantom phase era for cyclic universe. Consid-ering deceleration parameter tells us that the universe has a deceleration phase after an acceleration phase, and NADE is able to produce a cyclic universe. Also it is found valuable to study generalized second law of thermodynamics. Since the loop quantum correction is taken account in high energ
