In this Letter we demonstrate that any interaction of pressureless dark matter with holographic dark energy, whose infrared cutoff is set by the Hubble scale, implies a constant ratio of the energy densities of both components thus solving the coincidence problem. The equation of state parameter is obtained as a function of the interaction strength. For a variable degree of saturation of the holographic bound the energy density ratio becomes time dependent which is compatible with a transition from decelerated to accelerated expansion.

  1. Inflation in non-local hybrid metric-Palatini gravity

    hep-th 2024-12 conditional novelty 6.0 of 10

    Non-local hybrid metric-Palatini gravity generically contains ghosts, but a degenerate subclass with metric f(R) gravity plus Palatini non-local terms is ghost-free and can drive slow-roll inflation resembling Starobi...

  2. Hints Beyond $\Lambda$CDM from Barrow and Tsallis Holographic Dark Energy with GO cutoff

    gr-qc 2026-01 conditional novelty 5.0 of 10

    Barrow holographic dark energy with the Granda-Oliveros cutoff fits current background data as well as ΛCDM and shows a weak AIC preference only for the Union3-based dataset combination.

  3. Dynamical system analysis of the cosmological phases in Palatini $k$-essence gravity

    gr-qc 2025-11 unverdicted novelty 5.0 of 10

    Dynamical systems analysis of a Palatini k-essence model identifies fixed points for quasi-de-Sitter epochs, scaling solutions, and quintessence phases connected by heteroclinic orbits in flat FLRW cosmology.

    gr-qc 2025-06 conditional novelty 5.0 of 10

    Barrow and Tsallis holographic dark energy models fit DESI DR2 data but are disfavored by information criteria versus LambdaCDM and do not ease the Hubble tension.

  5. Topological dark energy from black-hole formations and mergers through the gravity-thermodynamics approach

    gr-qc 2024-12 reject novelty 5.0 of 10

    Black hole formation and merger, through topology changes of the cosmic apparent horizon, generate an effective dark energy whose equation of state is phantom-like or quintessence-like depending on the sign of the Gau...

    gr-qc 2026-07 unverdicted novelty 4.0 of 10

    Dynamical systems analysis shows loop quantum cosmology removes stable attractors in interacting dark energy-dark matter models that exist under classical gravity.

  7. Revisiting the Hubble tension problem in the framework of holographic dark energy

    astro-ph.CO 2025-11 unverdicted novelty 4.0 of 10

    HDE models with future event horizon IR cutoff partially ease the Hubble tension while Hubble-scale cutoffs do not, consistent across six models and multiple BAO/SN/CMB combinations.

  8. Solving an Interacting Quintessence Model with a Sound Horizon Initial Condition and its Observational Constraints

    gr-qc 2025-07 conditional novelty 4.0 of 10

    An interacting quintessence model with initial conditions set by the CMB sound horizon angle increases H0 with coupling strength, but observational constraints show it does not resolve the H0 or S8 tensions.
