Any non-gravitational coupling between dark matter and dark energy modifies the cosmological dynamics. Interactions in the dark sector are considered to be relevant to address the coincidence problem. Moreover, in various models the observed accelerated expansion of the Universe is a pure interaction phenomenon. Here we review recent approaches in which a coupling between both dark components is crucial for the evolution of the Universe.

  1. Exploring parametrized dark energy models in interacting scenario

    gr-qc 2025-05 reject novelty 4.0 of 10

    An interacting dark energy model with a linear equation-of-state parametrization is fitted to low-redshift data, yielding a fitted H0 of 75.6 for one dataset, but the model's H(z) does not satisfy its own Friedmann eq...
