We study cosmological dynamics of the energy-momentum squared gravity. By adding the squared of the matter field’s energy-momentum tensor (ζ T) to the Einstein Hilbert action, we obtain the Einstein’s field equations and study the conservation law. We show that the presence of ζT term, breaks the conservation of the energy-momentum tensor of the matter fields. However, an effective energy-momentum tensor in this model is conserved in time. By considering the FRW metric as the background, we… Expand
