Reconstruction of Ghost Scalar Fields

Authors: Mustafa Salti

In literature, a large number of approaches have been done to reconstruct the potential and dynamics of the scalar fields by establishing a connection between holographic/Ricci/new agegraphic/ghost energy density and a scalar eld model of dark energy. In most of these attempts, the analytical form of the potentials in terms of the scalar eld have not been reconstructed due to the complexity of the equations involved. In the present work, we establish a correspondence between ghost dark energy and quintessence, tachyon and dilaton scalar eld models in anisotropic Bianchi type-I universe to reconstruct the dynamics of these scalar fields.
