Abstract
A large number of scalar eld ideas have been introduced in literature in order to discuss the speedy expansion nature of our universe. Scalar eld denitions naturally come forward in particle physics. Fundamental particle physics theories can yield various scalar eld descriptions, but they do not dene its self-interacting potential exactly due to the complexity of corresponding equations. Here, we mainly focused on the reconstruction of the tachyon scalar eld dark energy prescription by making use of the variable generalized Chaplygin gas (VGCG) dark energy model in the four-dimensional (4D) spatially at Friedmann-Robertson-Walker (FRW) framework.
