Generalized Holographic Dark Energy Model
In this paper, the model of the holographic Chaplygin gas has been extended to two general cases: first the case of a modified variable Chaplygin gas and second the case of the viscous generalized Chaplygin gas. The dynamics of the model is expressed by the use of scalar fields and scalar potentials.
متن کاملGeneralized Interacting Holographic Dark Energy Model
In this manuscript, we present a generalization of the interacting holographic dark energy model using two equations of states for the dark energy: the modified variable Chaplygin gas and the viscous generalized Chaplygin gas. The dynamics of the model are expressed by the use of scalar fields and the scalar potentials. PACS numbers: 98.80.Cq, 98.80.-k, 98.80.Jk ∗[email protected]
متن کاملHolographic Dark Energy Model with Modified Generalized Chaplygin Gas
We present a holographic dark energy model of the universe considering modified generalized Chaplygin gas (GCG). The modified GCG behaves as an ordinary barotropic fluid in the early epoch when the universe was tiny but behaves subsequently as a ΛCDM model at late epoch. An equivalent model with scalar field is obtained here by constructing the corresponding potential. The holographic dark ener...
متن کاملHolographic Dark Energy Model with Generalized Chaplygin Gas
We present a holographic dark energy model of the universe considering modified extension of the generalized Chaplygin gas (GCG). The modified GCG behaves as an ordinary barotropic fluid in the early epoch when the universe was tiny but behaves subsequently as a ΛCDMmodel as the universe grows. We determine the corresponding holographic dark energy field and its potential. The stability of the ...
متن کاملStatefinder diagnostic for holographic dark energy model
In this paper we study the holographic dark energy model proposed by Li from the statefinder viewpoint. We plot the evolutionary trajectories of the model with c = 1 in the statefinder parameter-planes. The statefinder diagrams characterize the properties of the holographic dark energy and show the discrimination between this scenario and other dark energy models. We also perform a statefinder ...
