Contribution

It introduces a supergravity-based approach to holographic dark energy models with novel interaction terms and cutoff choices.

Findings

Models can be consistently embedded in supergravity

Different infrared cutoffs lead to distinct cosmological behaviors

Interactions influence the evolution of dark energy and dark matter

Abstract

We embed models of holographic dark energy coupled to dark matter in minimal supergravity plus matter, with one chiral superfield. We analyze two cases. The first one has the Hubble radius as the infrared cutoff and the interaction between the two fluids is proportional to the energy density of the dark energy. The second case has the future event horizon as infrared cutoff while the interaction is proportional to the energy density of both components of the dark sector.
