A non-singular bouncing cosmology in f (R, T) gravity

JK Singh, A Singh, A Beesham, H Shabani - Annals of Physics, 2023 - Elsevier
We investigate a bounce realization in the framework of higher order curvature in f (R, T)
modified theory of gravity. We perform a detailed analysis of the cosmological parameters to
explain the contraction phase, the bounce phase, and the expansion phase. Furthermore,
we observe a violation of the null energy condition, instability of the model, and a singularity
upon deceleration at the bouncing point, which are the supporting results for a bouncing
cosmology. The equation of state parameter exhibits a ghost condensate behavior of the …
