Resembling holographic dark energy with f(R)gravity as scalar field and ghost dark energy with tachyon scalar fields

摘要

In this article,the dynamics and potential of two different scalar fieldmodels is presented in a at Friedmann-Lemaitre-Robertson-Walker(FLRW) universe.One of those models is obtained from the corresponding relation betweenholographic energy density (HED) with energy density of the correspondingscalar field of f(R) gravity,and other models is achieved from connectionbetween the ghost energy density (GDE) with energy density of the tachyon fieldmodel. Also, a f(R) model according to the the HDE model is calculated thenstability,anti -gravity and viable conditions on it are investigated.
