Reconstruction of some cosmological models in f(R,T) cosmology

In this paper, we reconstruct cosmological models in the framework of f ( R , T ) gravity, where R is the Ricci scalar and T is the trace of the stress-energy tensor. We show that the dust fluid reproduces Λ CDM, phantom–non-phantom era and phantom cosmology. Further, we reconstruct different cosmol...

Summary:In this paper, we reconstruct cosmological models in the framework of f ( R , T ) gravity, where R is the Ricci scalar and T is the trace of the stress-energy tensor. We show that the dust fluid reproduces Λ CDM, phantom–non-phantom era and phantom cosmology. Further, we reconstruct different cosmological models, including the Chaplygin gas, and scalar field with some specific forms of f ( R , T ). Our numerical simulation for the Hubble parameter shows good agreement with the BAO observational data for low redshifts, z <2.
