摘要:
In the current study, a theoretical model for non -interacting new Tsallis holographic dark energy is constructed using the Granda-Oliveros as the IR cutoff with specified scale factor a (t) t ) = [sinh (kt)] kt )] 1 n . The time -dependent deceleration parameter, with appropriate assumptions, yields this scale factor. The features of the deceleration parameter, equation of state parameter, density parameter, and jerk parameter are then investigated for this model. According to our findings, the cosmos has a normal thermal history, dark matter and dark energy eras occurring one after the other until dark energy eventually takes over entirely in the far future. Additionally, the evolution of the potential and pressure to indicate the universe's accelerated expansion by using our model are studied. We investigate the evolution trajectory of statefinder parameters, which is consistent with ACDM model.
