Extending Anisotropic Interiors admitting Vanishing Complexity in Charged f (R, T) Theory
This paper extends the definition of the complexity factor for a charged self-gravitating structure in the background of gravity. For this purpose, the modified Einstein-Maxwell field equations and the mass function in terms of interior charge are calculated corresponding to a static sphere. The Reissner-Nordström exterior spacetime and match it with the spherical interior at the hypersurface to determine the junction conditions are adopted then. The curvature tensor is also decomposed orthogonally, resulting in several scalar functions. Only encompasses all the required parameters and fulfills the proposed criteria to be the complexity factor for the considered setup is noticed. Moreover, some constraints to minimize the degrees of freedom in the field equations are chosen. To achieve this, complexity-free constraint with four additional conditions depending on the matter sector that lead to different models is employed. The stability of the developed models is also analyzed in the presence and absence of charge through the standard model by varying the values of the model parameter . The presence of charge in compact models corresponding to , a polytropic and a linear equation of state make them stable for specific values of is concluded.
期刊介绍:
The journal Fortschritte der Physik - Progress of Physics is a pure online Journal (since 2013).
Fortschritte der Physik - Progress of Physics is devoted to the theoretical and experimental studies of fundamental constituents of matter and their interactions e. g. elementary particle physics, classical and quantum field theory, the theory of gravitation and cosmology, quantum information, thermodynamics and statistics, laser physics and nonlinear dynamics, including chaos and quantum chaos. Generally the papers are review articles with a detailed survey on relevant publications, but original papers of general interest are also published.
