Study of anisotropic universe in presence of DBI-essence, phantom and tachyonic fields

Abstract

This work is devoted to study the roles of Dirac–Born–Infeld (DBI)-essence, scalar field, phantom field, normal tachyonic field and phantom tachyonic field models driving the present expansion of the universe with acceleration in anisotropic background. To understand the different phase of the Bianchi I universe, the statefinder parameters and deceleration parameter are investigated diagrammatically. The radiation era to [Formula: see text]CDM model has been generated. The anisotropic parameters are analyzed during the evolution of the universe. It has been shown that DBI-essence, scalar field, phantom field, normal tachyonic field and phantom tachyonic field play an active role of dark energy which causes the acceleration of the anisotropic universe.
