Description

The study aims to reconstruct the scalar field model of Dark Energy (DE) namely tachyon, k-essence and dilation scalar field models of DE through holographic dark fluid under Chern-Simon's Modified Gravity. $\Lambda$CDM fixed point is attained in case of tachyon scalar field model under this cosmological settings $[1-8]$. Some constraints have been derived on the interaction term as Tsallis Holographic DE parameter in the interacting scenario by considering k-essence scalar field model. Equation of State (EoS) parameter for all the cases have been deduced and found to be consistent with the observational data from Planck+WP+BAO for current universe i.e., at $z=0$. Exception is that, the behaviour of reconstructed scalar field model is phantom $[9-13]$. Evolutionary behaviour of reconstructed scalar field and potential for various cases have been plotted and studied.
