Dark Matter and Holographic Dark Energy Models in Different Scenarios of the Universe

Pramod P. Khade | Amrapali P. Wasnik ^[2]

Abstract: In this paper we examine homogeneous and anisotropic Bianchi type-V universe filled with interacting Dark matter and Holographic dark energy. Here we express a scale factor in emergent, logamediate, and intermediate scenarios, under which the universe expands differently. It is shown that for suitable choice of interaction between dark matter and holographic dark energy there is no coincidence problem (unlike CDM). Also, in all the resulting models the anisotropy of expansion dies out very quickly and attains isotropy after some finite time. The physical and geometrical aspects of the models are also discussed.
