    Behavior of Magnetized Strange Quark Matter in 5D Cosmological Model
    (Springer Int Publ Ag, 2022) Kalkan, Sinem; Aktaş, Can
    In this study, distribution of magnetized strange quark matter is investigated for Kaluza-Klein universe within the framework of f(R, T) theory. Hubble parameter is used in the solution of f(R, T) field equations. The results obtained have been harmonized with the current values of the deceleration parameter and the evolution of the cosmic universe has been examined with the help of graphics and tables. When t -> infinity, we have obtained the value of the cosmological term very small. Also, we have examined the energy conditions for magnetized strange quark matter distribution.

    Bianchi V I0 Universe with Magnetized Strange Quark Matter in f(R, T) Theory
    (2021) Kalkan, Sinem; Aktaş, Can
    This study discusses f(R, T) theory, one of the alternative theories. It\rthen studies magnetized strange quark matter in the universe model Bianchi V I0,\rhomogeneous and anisotropic. Afterwards, it has determined whether the energy\rconditions are provided by using the deceleration parameter while obtaining the solutions.\rMoreover, the evolution of the cosmic universe is examined with the help of\rgraphics and tables.

    Does magnetized strange quark matter exist in the early universe?
    (World Scientific Publ Co Pte Ltd, 2022) Kalkan, Sinem; Aktaş, Can; Aygün, Sezgin
    In this paper, we have examined the magnetized strange quark matter (MSQM) distribution in the inhomogeneous anisotropic Einstein-Rosen universe model within the framework of f(R,T) theory and General Relativity (GR) in order to investigate whether there was a magnetic field in the first moments of the universe. With the help of the arbitrary F(r) function, we researched for solutions in both theories for various cases. We have seen that the cubic function F(r) = r(3) gives meaningful results in both theories. We have obtained magnetic field-free strange quark matter solutions for the quadratic and constant states of the arbitrary function F(r). It is seen that the choice of geometry (selection of the F(r) function) has an effect on the presence of the magnetic field. Finally, the physical results are examined on 3D graph.

    Manyetize acayip kuark maddenin f(R,T) teorideki davranışı
    (Çanakkale Onsekiz Mart Üniversitesi, 2022) Kalkan, Sinem; Aktaş, Can
    Bu çalışmada, manyetize acayip kuark maddenin davranışı 4 boyutlu homojen anizotropik Bianchi $VI_0$ uzay-zamanı ve 5 boyutlu homojen anizotropik Kaluza-Klein uzay-zamanı için $f(R,T)$ teori çerçevesinde incelendi. Her iki uzay-zaman için elde edilen çözümler matematiksel, geometrik ve fiziksel olarak irdelendi. Elde edilen sonuçlar, grafikler ve tablolar yardımıyla ayrıntılı bir şekilde analiz edildi. Ayrıca elde edilen çözümlerin enerji koşullarını sağlayıp sağlamadığı kontrol edildi.
