Ricci dark energy in bumblebee gravity model

Understand

The Ricci dark energy is a model inspired by the holographic dark energy models with the dark energy density being proportional to Ricci scalar curvature.

• Here this model is studied in the bumblebee gravity theory.
• It is a gravitational theory that exhibit spontaneous Lorentz symmetry breaking.
• Then the modified Friedmann equation is solved for two cases.
