Model parameters in the context of late time cosmic acceleration in $f(Q,T)$ gravity

Understand

The dynamical aspects of some accelerating models are investigated in the framework of an extension of symmetric teleparllel gravity dubbed as f(Q,T) gravity.

• In this gravity theory, the usual Ricci tensor in the geometrical action is replaced by a functional f(Q,T) where Q is the non-metricity and T is the trace of the energy-momentum tensor.
• Two different functional forms are considered in the present work.
• In order to model the Universe, we have considered a signature flipping deceleration parameter simulated by a hybrid scale factor (HSF).
