Barrow Holographic Dark Energy with Hybrid Expansion Law
Mayank Srivastava, Mukesh Kumar, Shikha Srivastava
Abstract
We investigate the Barrow holographic dark energy (BHDE) model using IR cutoff as the Hubble horizon in the background of a flat Friedmann–Lemaître–Robertson–Walker universe. The deceleration parameter exhibits the universe evolution from decelerated to accelerated phase. The EoS parameter of the BHDE model presents a nice behavior as it lies in the phantom era ( $$\omega_{B}<-1$$ ) and the quintessence era ( $$\omega_{B}\geq-1$$ ) for different values of the Barrow parameter $$\Delta$$ . The squared sound velocity $$v_{s}^{2}$$ has been investigated for the stability of the model. In addition, a correspondence with the phantom and quintessence scalar fields has been studied for the model, which helps us to describe the accelerated expansion of the universe.
