Thermodynamic aspects of the nonlinear electrodynamics models

In this paper, we consider the nonlinear radiation defined by power law and rational nonlinear electrodynamics (NLE) Lagrangian in homogeneous and isotropic background. These forms of NLE Lagrangian have been studied by using the numerical solution technique to explore the cosmic dynamics in models with matter and dark energy. The universe composed of decelerating and accelerating phases in these models has been examined to understand the evolution of total entropy enclosed by the apparent horizon. The validity of generalized second law of thermodynamics (GSLT) in different cosmic eras of NLE models with and without dark energy has been studied with their corresponding differences.
