| Abstract: | In this work, we have considered the DBI-essence dark energy model in FRW Universe. We have found the exact solutions of potential,
warped brane tension and DBI scalar field. We also calculate the statefinder parameters for our model that make it distinguishable
among numerous dark energy models. Moreover, we establish correspondence between DBI-essence and modified Chaplygin gas (MCG)
and hence reconstruct the potential and warped brane tension. By this reconstruction, we observe that DBI scalar field and
potential increase and warped brane tension decreases during evolution of the Universe. Finally, we investigate the validity
of the generalized second law (GSL) of thermodynamics in the presence of DBI-essence and modified Chaplygin gas. It is observed
that the GSL breaks down for DBI-essence model but GSL always satisfied for MCG model. |
