Holographic Chaplygin gas model

Abstract

In this paper we consider a correspondence between the holographic dark energy density and Chaplygin gas energy density in FRW universe. Then we reconstruct the potential and the dynamics of the scalar field which describe the Chaplygin cosmology.Comment: 9 pages, no figure

Statefinder Description in Generalized Holographic and Ricci Dark Energy Models

“…a , where k(= 0, ±1) is the curvature index and R E is the radius of event horizon [12] and we get r(t) = sin( √ |k|RE /a) √ |k| . On the basis of the holographic principle proposed by [13] several others have studied holographic model for dark energy [14].…”

Holographic Dark Energy Model with Chaplygin Gas

“…[26] for α = 1, A = 0andn = 0. Now we consider that the scalar field model of dark energy described by modified variable Chaplygin gas which corresponds to holographic dark energy of the universe.…”

“…Thus to have a model consistent with observed universe one should adopt the covariant entropy bound and choose L to be event horizon [24]. Considering a correspondence of holographic dark energy and Chaplygin gas the field potential is reconstructed [25,26]. In this chapter we consider variable Chaplygin gas whose EOS is given by eq.…”

Phase space analysis of interacting dark energy in f(T) cosmology

“…We assume a phenomenological form of interaction between matter and dark energy since these are the dominant components of the cosmic composition, following [43][44][45][46][47]. The exact nature of this interaction is beyond the scope of the paper and unresolved till we obtain a consistent theory of quantum gravity.…”
