Dynamical analysis and statefinder of Barrow holographic dark energy

Understand

Based on the holographic principle and the Barrow entropy, Barrow holographic dark energy had been proposed.

• In order to analyze the stability and the evolution of Barrow holographic dark energy, we, in this paper, apply the dynamical analysis and statefinder methods to Barrow holographic dark energy with different IR cutoff and interacting terms.
• In the case of using Hubble horizon as IR cutoff with the interacting term $Q=\frac{\lambda}{H}\rho_{m}\rho_{D}$, we find this model is stable and can be used to describe the whole evolution of the universe when the energy transfers from the pressureless matter to the Barrow holographic dark energy.
• When the dynamical analysis method is applied to this stable model, an attractor corresponding to an accelerated expansion epoch exists and this attractor can behave as the cosmological constant.
