1302.1180 (H. Mohseni Sadjadi)

Notes on teleparallel cosmology with nonminimally coupled scalar field    [PDF]

H. Mohseni Sadjadi
We consider the spatially flat Friedmann-Lemaitre-Robertson-Walker space time in the teleparallel model of gravity and assume that the universe is filled nearly by cold dark matter and a nonminimally coupled scalar field with a power-law potential as dark energy. We investigate the possibility that the universe undergoes a transition from quintessence to phantom phase. An analytical solution for the scalar field is obtained and necessary conditions required for such a transition are discussed.
