Anisotropic fluid dynamics with vanishing complexity and expansion-free constraints: Exploring analytical solutions in charged modified gravity

In this paper, we study non-static spherically symmetric shear-free anisotropic dissipative fluid distribution coupled with Maxwell field equations to find the solutions for dynamical equations Herrera et al. (2023) in f(R) gravity and use a physically realistic model, i.e., f(R) = R+ delta R-2, where R represents the Ricci scalar. We compute gravitational mass (Misner-Sharp) to explore matching conditions. We also construct conservation equations for ordinary, effective dark source terms and electromagnetic stress-energy tensors using Bianchi identities in f(R) gravity. Further, we utilize constraints like vanishing expansion scalar and complexity factor to derive exact analytical solutions for gravitational equations in f(R) gravity.
