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 کاملGeneralized Model for Λ-Dark Energy
Einstein field equations under spherically symmetric space-times are considered here in connection to dark energy investigation. A set of solutions are obtained for a kinematical Λ model, viz., Λ ∼ (ȧ/a) without assuming any a priori value for the curvature constant and the equation of state parameter ω. Some interesting results, such as the nature of cosmic density Ω and deceleration parameter...
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 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...
