Axially Symmetric Universe Solutions with Strange Quark Matter in Creation-Field Cosmology
Abstract
This study investigates the axially symmetric universe model in the Creation Field of Cosmological theory. Strange quark matter is assumed as matter distribution by attaching a string cloud. The proportion of shear scalar $\sigma^2$ and expansion scalar $\theta$ have been used for the purpose of the study, and a relationship between scale factors $A(t)$ and $B(t)$ has been attained as $A=B^k$. The modified Einstein field equations have been solved using the constant deceleration parameter $q=m-1$. Besides, the solutions have been achieved at special conditions, such as the exponential expansion model of deceleration parameter $q=-1$. It has been drawn from the obtained results that, in the early universe, the scale factors $A$ and the spatial volume of the universe $V$ have a zero value at the initial time of the universe. Furthermore, these values have rapidly increased with cosmic time, confirming the expansion of the universe models. Moreover, some kinematic quantities have been investigated for the constructed models. All the results are discussed within the cosmological framework and supported by compatible studies.
