    "abstract": "A model is developed to explain the temperature dependence of the group\nvelocity as observed in the experiments of Hau et al (Nature {\\bf397}, 594\n(1999)). The group velocity is quite sensitive to the change in the spatial\ndensity. The inhomogeneity in the density and its temperature dependence are\nprimarily responsible for the observed behavior.",
