Asymptotic behavior of ω in general quintom model
نویسنده
چکیده
For the quintom models with arbitrary potential V = V (φ, σ), the asymptotic value of equation of state parameter ω is obtained by a new method. In this method, ω of stable attractors are calculated by using the ratio d lnV/d ln a in asymptotic region. All the known results, have been obtained by other methods, are reproduced by this method as specific examples.

Transition from quintessence to phantom phase in quintom model
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 ...
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...

متن کاملNon-minimally Coupled Quintom Model Inspired by String Theory
In this paper we consider a quintom model of dark energy with a single scalar field T given by a Lagrangian which inspired by tachyonic Lagrangian in string theory. We consider non-minimal coupling of tachyon field to the scalar curvature, then we obtain the equation of state (EoS), and the condition required for the model parameters when ω crosses over −1.

Considering the quintom model with arbitrary potential, it is shown that there always exists a solution which evolves from ω > −1 region to ω < −1 region. The problem is restricted to the slowly varying potentials, i.e. the slow-roll approximation. It is seen that the rate of this phase transition only depends on the energy density of matter at transition time, which itself is equal to the kine...
