Evolution of entropic dark energy and its phantom nature

Understand

Assuming the form of the entropic dark energy as arises form the surface term in the Einstein-Hilbert's action, it's evolution were analyzed in an expanding flat universe.

• The model parameters were evaluated by constraining model using the Union data on Type Ia supernovae.
• We found that the model predicts an early decelerated phase and a later accelerated phase at the background level.
• The evolution of the Hubble parameter, dark energy density, equation of state parameter and deceleration parameter were obtained.
