Dark energy model in higher-dimensional FRW universe with respect to generalized entropy of Sharma and Mittal of flat FRW space-time
(Canadian Science Publishing, 2019) Demirel, E. C. Gunay
In this study, we report the state parameter of dark energy in higher dimensional Friedmann-Robertson-Walker (FRW) space-time according to generalized entropy of Sharma and Mittal. In this case we analyze the state parameter of dark energy according to today's observational evidence.
Dark Matter And Dark Energy Solutions Using By Observational Evidence
(Amer Inst Physics, 2018) Demirel, E. C. Gunay; Yilmaz, I.
In this study, we examine dark energy, dark matter and baryonic matter in FRW by observational evidences. Also we study our model by considering possible dark energy candidates such as Phantom energy. Obtained solutions show that dark energy candidate may be phantom energy depending on accuracy of today's observation.
The Solutions And Thermodynamic Dark Energy In The Accelerating Universe
(Amer Inst Physics, 2016) Demirel, E. C. Gunay
Recently, Tachyonic matter expressed in terms of scalar field is suggested to be the reason of acceleration of the universe as dark energy [1]-[3]. In this study, dynamic solutions and thermodynamic properties of matters such as Tachyonic matters were investigated.
