کلیدواژه‌ها Dark energy Phantom Crossing
چکیده We study the possible crossing of the phantom divided barrier in a Lorentz invariance violating dark-energy model. Lorentz invariance violation, which is achieved by introducing a vector field in the action, incorporates directly in the dynamics of the scalar field and equation of state. This interesting feature allows us to study phantom divided barrier crossing in the context of Lorentz invariance violation. We show that for a suitable choice of the parameter space, the equation of state can cross the phantom divided barrier just by one scalar field and a Lorentz violating vector field controls this crossing.
