This paper is devoted to exploring exact charged solutions in a cloud of strings through minimal geometric deformation technique in three-dimensional gravity. For this purpose, we first evaluate the exact charged isotropic solution for static circular symmetry using Takabayashi equation of state and extend it to obtain three concrete anisotropic charged models. We investigate energy conditions as well as speed of sound constraint to check the viability of the respective solutions. it is concluded that the second model is a realistic one as it fulfills all the physical characteristics as well as stability criterion while the rest of two solutions do not satisfy the physical constraints.

Charged anisotropic fluid sphere in comparison with its uncharged analogue through extended geometric deformation
M. Zubair, Hina Azmat, Mobeen Amin
Summary: In this article, a known charged isotropic Durgapal IV solution is extended to its anisotropic version using the extended geometric deformation (EGD) approach. The physical properties of the anisotropic stellar model are studied and compared with its uncharged anisotropic analogue. The results show that the anisotropic stellar model is stable for a larger range of the coupling constant in the presence of electric charge, and the effects of anisotropy are diminished near the stellar surface.

Anisotropy and deformation of triply periodic minimal surface based lattices with skew transformation
Nan Yang, Zheng Qian, Huaxian Wei, Miao Zhao
Summary: This study proposes a skew transformation (ST) to distort TPMS lattices at the design stage, in order to modify their mechanical anisotropies and tailor their deformations under uniaxial loading. The ST method enables a standard TPMS lattice to increase the direction-dependent modulus without changing the lattice's volume fraction, which is 38% higher than the theoretical Hashin-Shtrikman upper (HSU) bound for a sheet lattice. Furthermore, the ST method can be used to texture the local deformation, stress distribution, and failure form by constructing a cellular mechanical metamaterial.

Monopoles, strings and gravitational waves in non-minimal inflation
Rinku Maji, Qaisar Shafi
Summary: We discuss the survival of topologically stable intermediate mass monopoles in SO(10) grand unification during inflation, driven by a Coleman-Weinberg potential and non-minimal coupling to gravity. The model predicts an agreement with current observations of the scalar spectral index ns, and a tensor to scalar ratio r >= 0.003. It also suggests the presence of intermediate scale topologically stable cosmic strings, whose gravitational wave spectrum reflects the amount of cosmic inflation experienced during symmetry breaking.

Ariel Fuxman, Shai Gul
Summary: This study considers a family of generalized parabolas passing through a given point in the first quadrant and explores parameter values that result in either the minimum area or the minimum length of the corresponding parabola in the first quadrant. A sufficient condition is found where the curve minimizing the area and the curve minimizing the length coincide. The problem leads to an implicit function, and its asymptotic behavior and convexity are explored.

WGC and WCC for charged black holes with quintessence and cloud of strings
Mohammad Reza Alipour, Jafar Sadeghi, Mehdi Shokri
Summary: This paper tackles an important issue concerning the violation of cosmic censorship due to the existence of weak gravity conjecture (WGC). By considering charged black holes in four dimensions and in the normal state, the authors eliminate the violation of weak cosmic censorship conjecture (WCCC) and demonstrate a good compatibility between WGC and WCCC. Furthermore, it is shown that the case with quintessence and cloud of strings has more parameters and more freedom to establish the compatibility between the two theories, compared to the case with only quintessence.

Quantum phase space description of a cosmological minimal massive bigravity model
Julio Cesar Vera-Hernandez
Summary: In this study, the deformation quantization formalism was applied to a HR cosmological model in the minisuperspace, with explicit quantization procedures performed for quantum cosmology. The stability analysis in the quantum minisuper phase space revealed a new interpretation of the graviton mass as an emergent cosmological constant and a measure of classical behavior deviation. Additionally, an interesting relation between curvature and graviton mass in a cusp catastrophe surface was discussed specifically in the Hartle-Hawking case.

Numerical study on the anisotropy in thermo-fluid behavior of triply periodic minimal surfaces (TPMS)
Tao Zhang, Fei Liu, Kaifei Zhang, Miao Zhao, Hailun Zhou, David Z. Zhang
Summary: In this study, Gyroid and Diamond structures with different rotating angles were designed and fabricated using the implicit function method. The thermal and hydraulic behaviors were systematically studied and visually analyzed using computational fluid dynamics. The results showed that both Gyroid and Diamond structures exhibited apparent symmetry and the pressure gradient had a clear dependence on the rotating angle. However, the angular difference in heat transfer rate was not significant. Overall, this work provides valuable information for understanding the angular behavior of TPMS-based sandwich panels and their potential applications in various industries.

Charged anisotropic models with complexity-free condition
M. Sharif, Tayyab Naseer
Summary: This paper investigates the complexity of a static spherically symmetric spacetime and extends it to include charged distributions. The Einstein-Maxwell field equations for the anisotropic interior are formulated, and two different mass functions are calculated. The Reissner-Nordstrom metric is used as the exterior spacetime, and matching conditions at the spherical boundary are determined. The complexity factor, YTF, is defined as one of the scalars derived from the orthogonal splitting of the curvature tensor. Three independent field equations are not sufficient to close the system, so a complexity-free condition is adopted, along with three constraints leading to different models. The resulting solutions are interpreted graphically with specific parameter values, and it is concluded that models with pr = 0 and a polytropic equation of state exhibit viable and stable behavior everywhere.

Study of decoupled gravastars in energy-momentum squared gravity
M. Sharif, Saba Naz
Summary: In this paper, we construct an exact anisotropic gravastar model within the framework of f (R, T2) gravity, using the gravitational decoupling technique and minimal geometric deformation. This novel model provides a description of an ultra-compact stellar configuration that smoothly matches the internal and exterior regions. The developed stellar model satisfies important physical characteristics such as a monotonically decreasing energy density profile and pressure behavior. The anisotropic factor and Schwarzschild spacetime also exhibit physically acceptable behavior, except for the strong energy condition inside the ultra-compact stellar structure for a specific coupling constant, which is consistent with the regularity condition.

Study of Decoupled Cosmological Solutions in f(R,T) Theory
Tayyab Naseer, M. Sharif
Summary: In this paper, a non-static spherical geometry is considered and its extension for anisotropic matter configuration through minimal gravitational decoupling in f(R,T) theory is formulated. A particular transformation is applied to the radial metric function to divide the modified field equations into two distinct sectors corresponding to their parent sources. The unknowns in the isotropic set are reduced using the Friedmann-Lemaitre-Robertson-Walker cosmic model, and the isotropic solution is obtained using a linear equation of state and power-law form of the scale factor. The other set involves the decoupling function and components of an extra source, and a density-like constraint is adopted to close it. The role of this modified gravity and the decoupling parameter on three different eras of the cosmos is analyzed by graphically observing the developed extended solution, and it is concluded that the resulting solutions fulfill all the physical requirements only for the matter and radiation-dominated eras.

M. Sharif, M. Zeeshan Gul
Summary: This paper examines the feasible properties of charged compact stars with anisotropic matter configuration in f(R,T2) theory. The study applies the embedding class-1 technique and focuses on a specific functional form, f(R,T2)=R-gamma T2), to analyze the geometry of compact objects. By smoothly matching the interior and exterior spacetimes, the values of unknown parameters are determined. The research investigates the impact of anisotropy in effective fluid parameters, equation of state parameters, and energy bounds in the inner region of charged stellar objects. The stability of the charged anisotropic stellar objects in this modified theory is examined using the speed of sound and adiabatic index. The findings suggest that the embedding class-1 solution is physically viable and stable for charged anisotropic stellar objects in this modified theory.

Traversable wormhole solutions admitting Karmarkar condition in f(R, T) theory
M. Sharif, Arooj Fatima
Summary: In this paper, the authors evaluate traversable wormhole solutions in f(R, T) theory using the Karmarkar condition, where T is the trace of the energy-momentum tensor and R represents the Ricci scalar. They develop a wormhole shape function for static traversable wormhole geometry using the embedding class-I technique. The resulting shape function is used to construct a wormhole geometry that satisfies all necessary conditions and connects two asymptotically flat regions of spacetime. They investigate the existence of viable and stable traversable wormhole solutions with anisotropic matter configuration and different f(R, T) gravity models, and analyze the graphical behavior of null energy bound to determine the presence of physically viable wormhole geometry. The study shows that viable and stable traversable wormhole solutions exist in this modified theory of gravity.

Muhammad Sharif, Muhammad Zeeshan Gul
Summary: The article investigates the stability of the Einstein static universe using inhomogeneous perturbations in the context of energy-momentum squared gravity. Formulating static and perturbed field equations in the FRW spacetime with perfect matter distribution, a minimal model is used to examine the stable regions of the Einstein universe for conserved and non-conserved energy-momentum tensors. The study finds stable modes in both cases for all values of the equation of state and model parameters, indicating a broader Ω-region compared to other modified theories.

Summary: In this paper, two anisotropic static spherical solutions for two compact stellar candidates in the background of f(G,T) gravity are computed using the minimal geometric decoupling technique. The internal structure becomes anisotropic when an additional sector is added. The physical feasibility and stability of the resulting anisotropic solutions are examined through energy conditions and stability criteria, and it is found that the compact star Her X-1 is viable but not stable for the first solution, while the star 4U 1820-30 indicates viable and stable behavior for both anisotropic solutions.

Stable gravastars with Krori-Barua metric in f (R, T2) gravity
M. Sharif, Saba Naz
Summary: This paper explores the physical attributes of charged gravastar in the context of f (R, T2) gravity. Gravastar, an alternative to black hole, consists of internal and external domains with a separating shell region. Different values of the equation of state parameter are used to describe each region. A specific model is constructed and Israel matching criteria is employed to ensure smooth joining of the inner and outer geometries. The effects of shell thickness (length, entropy, and energy) on gravastar attributes in the presence of charge are discussed. It is concluded that charged gravastar structure exhibits acceptable behavior in this modified theory of gravity.

By using Finch-Skea symmetry and considering different f (7z, T2) models, the physical characteristics of compact stars are examined.

Constraints are applied to solve the equations, and the impact of charge and decoupling parameter on the physical characteristics in the interior of a compact model is analyzed. The first model is found to be physically relevant for all parameter choices, while the second solution becomes unstable only for = 1.
