英文摘要	Recent observations of the Cosmic Microwave Background, Supernovae and Sloan Digital Sky Survey (SDSS) show that our universe has a critical energy density, and roughly 2/3 of it is dark energy, which drives the accelerating expansion of the cosmos. In view of the astrophysical data, we find that the equation of state parameter of the dark energy lies in a narrow range around w = -1. In this paper, we construct a cosmology model with a Rarita-Schwinger field to realize the equation of state parameter w < -1 or w < -1 and discuss its stability.
