Non-interacting Barrow-holographic dark energy in FRW-universe with quintessence behavior.

In order to analyze Barrow holographic dark energy (BHDE) in a flat FRW universe, the time-dependent scale factor a (t) = [ sinh (α t) ] 1 n is employed. The Hubble horizon as the IR-cutoff is taken to investigate the cosmic consequences. We demonstrate the cosmic transition using the deceleration parameter and equation of state parameter. The characteristics of deceleration parameter for this model correspond well with the latest findings. The equation of state parameter behaves well and does not cross the phantom line. Depending on the values of Barrow exponent (Δ), our model is entirely quintessence and is eventually moving towards Λ -CDM model. We plotted the pressure diagram with various Barrow exponent (Δ) values to demonstrate dark energy dominance. The scalar field and potential that explain the universe's accelerating expansion are also reconstructed. [ABSTRACT FROM AUTHOR]
