Abstract.

We study the traversable wormhole solutions by using a phantom-like generalized cosmic chaplygin gas and discuss their viability. This equation of state can explain the late-time cosmic acceleration through a variety of useful parameters and also has the ability to violate the null energy condition. In this scenario, we find wormhole solutions for the constant as well as variable redshift function and also for the isotropic case. We use the volume integral quantifier, which indicates the presence of phantom energy in a given wormhole solution. It is interesting to mention here that we are able to construct the traversable, asymptotically flat and stable wormhole solutions.
