Hybrid Chaplygin gas model is put forward, in which the gases play the role of dark energy. For this model the coincidence problem is greatly alleviated. The effective equation of state of the dark energy may cross the phantom divide w = -1. Furthermore, the crossing behavior is decoupled from any gravity theories. In the present model, w < -1 is only a transient behavior. There is a de Sitter attractor in the future infinity. Hence, the big rip singularity, which often afflicts the models with…

Observational constraints on Chaplygin cosmology in a braneworld scenario with induced gravity and curvature effect
We study cosmological dynamics and late-time evolution of an extended induced gravity braneworld scenario. In this scenario, curvature effects are taken into account via the Gauss–Bonnet term in the
Interacting modified variable Chaplygin gas in a non-flat universe
A unified model of dark energy and matter is presented using the modified variable Chaplygin gas for interacting dark energy in a non-flat universe. The two entities interact with each other
New mechanism to cross the phantom divide
Recently, type Ia supernova data appear to support a dark energy whose equation of state w crosses −1, which is a much more amazing problem than the acceleration of the universe. We show that it is
The osgood criterion and finite‐time cosmological singularities
In this paper, we apply Osgood's criterion from the theory of ordinary differential equations to detect finite‐time singularities in a spatially flat FLRW universe in the context of a perfect fluid,
On Perturbations of Quintom Bounce
A Quintom universe with an equation-of-state crossing the cosmological constant boundary can provide a bouncing solution dubbed the Quintom Bounce and thus resolve the Big Bang singularity. In this
ΛCDM, ΛDGP and extended phantom-like cosmologies
TLDR
It is shown that the accelerating phase of the universe in the f(R)-DGP scenario is stable if one consider the curvature fluid as a phantom scalar field in the equivalent scalar-tensor theory, otherwise it is a transient and unstable phenomenon.

Interacting Chaplygin gas
We investigate a kind of interacting Chaplygin gas model in which the Chaplygin gas plays the role of dark energy and interacts with cold dark matter particles. We find that there exists a stable
Cosmological evolution of "hessence" dark energy and avoidance of the big rip
Recently, many dark energy models whose equation-of-state parameter can cross the phantom divide w(de)=-1 have been proposed. In a previous paper [H. Wei, R. G. Cai, and D. F. Zeng, Classical Quantum
Letter: Density Perturbations in a Universe Dominated by the Chaplygin Gas
We study the fate of density perturbations in a Universe dominate by the Chaplygin gas, which exhibit negative pressure. In opposition to other models of perfect fluid with negative pressure, there
An Interacting Two-Fluid Scenario for Quintom Dark EnergyThe project supported by National Natural S
The Quintom dark energy is a proposal that explains the recent observations that mildly favor the equation of state of dark energy w crossing -1 near the past. The Quintom model is often constructed
Revival of the unified dark energy–dark matter model?
We consider the generalized Chaplygin gas (GCG) proposal for unification of dark energy and dark matter and show that it admits an unique decomposition into dark energy and dark matter components
Generalized Chaplygin gas as a unified scenario of dark matter/energy: Observational constraints
Although various cosmological observations congruously suggest that our universe is dominated by two dark com- ponents, the cold dark matter without pressure and the dark energy with negative
