New type scalar fields for cosmic acceleration
arXiv:hep-th/0606051 · doi:10.1088/1742-6596/68/1/012017
Abstract
We present a model where a non-conventional scalar field may act like dark energy leading to cosmic acceleration. The latter is driven by an appropriate field configuration, which result in an effective cosmological constant. The potential role of such a scalar in the cosmological constant problem is also discussed.
