Energy conditions and stability of charged wormholes in f(R,ℒm) gravity: A comparative analysis with compact objects

In this paper, we study the energy conditions of charged traversable wormholes in the framework of [Formula: see text] modified gravity. In the first case, we derive the shape functions (SFs) for two different choices of the charge function [Formula: see text] by considering the exponential spheroid (ES) model and analyze the null energy condition (NEC). In the second case, we consider a particular SF and study its implications for the energy conditions. In both cases, we obtain expressions for energy density and pressure in radial and tangential directions. Our findings show that the radial NEC remains satisfied across a wide range of charge parameters [Formula: see text] consistent with established physical laws. However, the tangential NEC is only sustained in the range [Formula: see text]; for higher charge values, violations occur, indicating the formation of a throat-like structure necessary for wormhole stability. Additionally, we compare the pressure-density profiles of these charged wormholes with those of compact objects such as neutron stars, revealing distinct variations in matter distribution. This analysis highlights the crucial role of charge and modified gravity in determining the stability and physical characteristics of wormhole structures.
