Abstract
A new class of scalar field model was explored with novel dynamical properties that avoided the fine tuning problem, in case of small cosmological constant and late-time cosmic acceleration. A feature of these models was that negative pressure resulted from the nonlinear kinetic energy of the scalar field.
