Description
This work investigates the cosmological application of interacting modified Chaplygin gas in the f(T) gravity framework, where T is the torsion scalar. The interacting MCG has been found to have the equation of state (EoS) parameter behaving like quintessence. However, the f(T) gravity reconstructed via the interacting MCG has been found to have EoS crossing the phantom boundary of -1. Thus, one can generate a quintom-like EoS from an interacting MCG model in the flat universe in the modified gravity cosmology framework. Cosmological evolution of primordial perturbations has also been investigated and the self-interacting potential has been found to increase with cosmic time and the squared speed of sound has been found to be non-negative.
