Correspondence of F-essence with Chaplygin gas cosmology

摘要

In this work, we have considered generalized cosmic Chaplygin gas (GCCG) and new variable modified Chaplygin gas (NVMCG) types of dark energies in the framework of F-essence cosmology and investigated the consequences for their co-existence. The correspondence of the F-essence with the above types of Chaplygin gas models has been investigated. The natures of K and Y for this correspondence of the F-essence with all the gases have been analyzed graphically. From the graphical representation, we demand that K always increases with Y due to correspondence, and the EoS parameter w shows that the F-essence model always gives only quintessence type of dark energy and phantom crossing does not happen in our constructed models.
