Dynamics of Mixed Dark Energy Domination in Teleparallel Gravity and Phase-Space Analysis
arXiv:1610.04608 · doi:10.1155/2015/608252
Abstract
We consider a novel dark energy model to investigate whether it will provide an expanding universe phase. Here we propose a mixed dark energy domination which is constituted by tachyon, quintessence, and phantom scalar fields nonminimally coupled to gravity, in the absence of background dark matter and baryonic matter, in the framework of teleparallel gravity. We perform the phase-space analysis of the model by numerical methods and find the late-time accelerated attractor solutions implying the acceleration phase of universe.
