abstract
The problem of the cosmic coincidence is a longstanding puzzle. This conundrum may be solved by introducing a coupling between the two dark sectors. In this Letter, we study a coupled quintessence scenario in which the scalar field evolves in a power law potential and the mass of dark matter particles depends on a power law function of $\phi$. It is shown that this scenario has a stable attractor solution and can thus provide a natural solution to the cosmic coincidence problem.

Robust Preference for Dark Sector Interactions
Interacting dark matter–dark energy models fit DESI BAO and CMB data as well as evolving-dark-energy (CPL) models, with a coupling preference that persists under DES-Dovekie supernova recalibration.

Model-independent late-universe measurements of $H_0$ and $\Omega_K$ with the parametrization based on cosmic age-improved inverse distance ladder
A cosmic-age-based inverse distance ladder with DESI DR2, DESY5, SGL, CC and GRB data gives H0=71.59±0.94 km/s/Mpc and ΩK=0.001±0.038.

Neutrino mass constraints in the Schwarzschild-de Sitter black-hole dark energy model with ACT DR6 and DESI DR2 data
SdSDE dark energy yields a ~0.16–0.21 eV positive neutrino-mass preference with DESI+ACT data, but χ² strongly favors extended ΛCDM and the shift is likely compensation.

Neutrino mass constraints in interacting dark energy models after DESI DR2
Upper bounds on total neutrino mass in four phenomenological interacting dark energy models are derived from DESI DR2 BAO plus CMB and SNIa data, showing strong dependence on the interaction term form and statistical ...

Alleviating the $H_0$ tension through the interacting dark energy model from quantum gravitational field theory in light of DESI DR2
With DESI DR2 BAO plus CMB and a SH0ES prior, the two-parameter eeΛCDM model gives δΛ=-0.41±0.14 and H0=71.9±1.0, easing the Hubble tension to 0.8σ, but SN datasets erase the signal.

The model-independent degeneracy-breaking point in cosmological models with interacting Dark Energy and Dark Matter
In interacting dark energy models, the interaction term becomes independent of the constant dark energy equation of state at a specific redshift (about z=1.4), giving a point where the interaction can be observed with...
