Transition from quintessence to phantom phase in quintom model
نویسنده
چکیده
Assuming the Hubble parameter is a continuous and differentiable function of comoving time, we investigate necessary conditions for quintessence to phantom phase transition in quintom model. For powerlaw and exponential potential examples, we study the behavior of dynamical dark energy fields and Hubble parameter near the transition time, and show that the phantom-divide-line ω = −1 is crossed in these models.

In this paper we will investigate the validity of the Generalized Second Law of thermodynamics for the Quintom model of dark energy. Reviewing briefly the quintom scenario of dark energy, we will study the conditions of validity of the generalized second law of thermodynamics in three cases: quintessence dominated, phantom dominated and transition from quintessence to phantom will be discussed.
متن کاملQuintom models with an equation of state crossing − 1
In this paper, we investigate a kind of special quintom model, which is made of a quintessence field φ1 and a phantom field φ2, and the potential function has the form of V (φ 2 1 − φ2). This kind of quintom fields can be separated into two kinds: the hessence model, which has the state of φ1 > φ 2 2, and the hantom model with the state φ 2 1 < φ 2 2. We discuss the evolution of these models in...

In this paper, we study a kind of special quintom models, which are made of a quintessence field φ 1 and a phantom field φ 2 , and their potential functions have the form of V (φ 2 1 − φ 2 2). These models have simple kinetic functions, so the analysis of them is simple. These models are separated into two kind: the hessence models, which have φ 2 1 > φ 2 2 , and the hantom, which have φ 2 1 < ...

By choosing the future event horizon as the horizon of the flat FLRW universe, we show that although the interacting holographic dark energy model is able to explain the phantom divide line crossing, but the thermodynamics second law is not respected in this model. We show that if one takes the particle event horizon as the horizon of the universe, besides describing ω = −1 crossing in a consis...
