Revisiting the dynamics of interacting vector-like dark energy

Understand

We revise the dynamics of interacting vector-like dark energy, a theoretical framework proposed to explain the accelerated expansion of the universe.

• By investigating the interaction between vector-like dark energy and dark matter, we analyze its effects on the cosmic expansion history and the thermodynamics of the accelerating universe.
• Our results demonstrate that the presence of interaction significantly influences the evolution of vector-like dark energy, leading to distinct features in its equation of state and energy density.
• We compare our findings with observational data and highlight the importance of considering interactions in future cosmological studies.
