Reconstruction of Potentials as Well as Dynamics of Scalar Fields in DGP Braneworld Model

Here, we investigate the cosmological implications of Holographic Dark Energy (HDE) in the DGP braneworld model of the universe. Taking HDE in DGP braneworld, we investigate the model of non-interacting dark energy and derive its equation of state. Subsequently, we study the correspondence between k-essence, tachyon, dilaton, hessence and DBI-essence dark energy with the non-interacting HDE in a flat DGP braneworld and reconstruct the corresponding scalar potentials which describe the dynamics of the scalar fields. Also we study the correspondence between above mentioned scalar potentials and effective dark energy coming from DGP braneworld in the absence of HDE and in this situation, the potentials are reconstructed.
