Abstract

In this letter we present a new form of the well known Chaplygin gas model by introducing inhomogeneity in the EOS. This model explains ω=1\omega=-1 crossing. Also we have given a graphical representation of the model using {r,s}\{r,s\} parameters. We have also considered an interaction of this model with the scalar field by introducing a phenomenological coupling function and have shown that the potential decays with time.
