### Cosmological evolution of a tachyon-quintom model of dark energy

- Physics, Mathematics
- 2009

In this work we study the cosmological evolution of a dark energy model with two scalar fields, i.e. the tachyon and the phantom tachyon. This model enables the equation of state w to change from w >…

### Dark energy model with spinor matter and its quintom scenario

- Physics
- 2008

A class of dynamical dark energy models, dubbed spinor quintom, can be constructed by a spinor field ψ with a nontraditional potential. We find that, if choosing suitable potential, this model is…

### On dark energy models of single scalar field

- Mathematics, Physics
- 2011

In this paper we revisit the dynamical dark energy model building based on single scalar field involving higher derivative terms. By imposing a degenerate condition on the higher derivatives in…

### RECONSTRUCTING A STRING-INSPIRED NONMINIMALLY COUPLED QUINTOM MODEL

- Mathematics, Physics
- 2009

Motivated by the recent work of Zhang and Chen,1 we generalize their work to the nonminimally coupled case. We consider a quintom model of dark energy with a single scalar field T given by a…

### Dynamical features of a quintom dark energy model with Galileon corrections

- PhysicsInternational Journal of Modern Physics D
- 2019

In this work, we propose a new dark energy cosmological model, by considering a new quintom scenario which is based on the superposition between a quintessence scalar field and a noncanonical scalar…

### Quintom Potentials from Quantum Cosmology Using the FRW Cosmological Model

- Physics
- 2013

We construct the quintom potential of dark energy models in the framework of spatially flat Friedmann–Robertson Walker universe in the inflationary epoch, using the Bohm like approach, known as…

### The past and future dynamics of quintom dark energy models

- Physics, MathematicsThe European Physical Journal C
- 2018

We study the phase space of the quintom cosmologies for a class of exponential potentials. We combine normal forms expansions and the center manifold theory in order to describe the dynamics near…

### TWO-FIELD MODELS OF DARK ENERGY WITH EQUATION OF STATE ACROSS -1

- Physics
- 2005

In this paper, we study the possibility of building two-field models of dark energy with equation of state across -1. Specifically we will consider two classes of models: one consists of two scalar…

### Crossing the w = - 1 barrier in the D3-brane dark energy model

- Physics
- 2005

We explore a possibility for the Universe to cross the w=-1 cosmological constant barrier for the dark energy state parameter. We consider the Universe as a slowly decaying D3-brane. The D3-brane…

In these notes we revisit the tachyon lagrangian in the open string field theory using background independent approach of Witten from 1992. We claim that the tree level lagrangian (up to second order…

### Dynamics of dark energy

- Physics
- 2006

We review in detail a number of approaches that have been adopted to try and explain the remarkable observation of our accelerating universe. In particular we discuss the arguments for and recent…
