Strange quark matter coupled to string cloud in Lyra geometry

Abstract

Hypersurface homogeneous cosmological models for strange quark matter coupled to string cloud in the framework of Lyra geometry have been presented. Exact solution of the field equations are obtained by considering various forms of the deceleration parameter found in the literature. It is observed that the rest energy density, particle energy density and string tension density are affected by displacement vector β. Physical parameters of the investigated model are also discussed.

Magnetized strange quark model with Big Rip singularity in f(R, T) gravity

“…46 Recently, many authors have also studied the properties of quark matter and strange quark matter in the account of general relativity as well as various modified gravitational theories. In general theory of relativity, the strange quark matter has been studied along with cosmic string cloud for axially symmetric space-time by Katore 50 and again attached to both string cloud and domain wall for spherically symmetric Kink space-time by Sahoo and Mishra. 51,52 In f (R) theory of gravity, the behaviour of quark and strange quark matter has been studied for Bianchi type-I and V space time by Yilmaz et al 47 and for Kantowski-Sachs metric by Adhav et al 48 In particular, Agrawal and Pawar 49 have studied the quark and strange quark matter for a LRS Bianchi I metric in f (R, T ) gravity.…”

Kasner type magnetized string cosmological models in f(R,T) gravity

“…Bali and Dave (2001) have studied cosmic string in context of the general relativity. Katore and Hatkar (2015) have investigated homoge-neous hypersurface with cosmic string in Lyra geometry. Naidu et al (2013) have obtained solutions for bulk viscous strings in the Brans-Dicke theory using the five dimensional Kaluza-Klein space time.…”
