Contribution

It introduces a novel correspondence between ghost and Chaplygin scalar field dark energy models in a non-flat FRW universe, including interaction with dark matter.

Findings

Reconstructed the scalar potential and dynamics for the Chaplygin model.

Demonstrated the model's ability to describe phantom accelerated expansion.

Analyzed the effects of spatial curvature and dark matter interaction.

Abstract

We investigate the correspondence between the ghost and Chaplygin scalar field dark energy models in the framework of Einstein gravity. We consider a spatially non-flat FRW universe containing the interacting dark energy with dark matter. We reconstruct the potential and the dynamics for the Chaplygin scalar field model according to the evolutionary behavior of the ghost dark energy which can describe the phantomic accelerated expansion of the universe.
