dc.description.abstractWe 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 model near the bouncing point. Additionally, we discuss the stability of the model using linear perturbations in the Hubble parameter as well as the energy density.
