abstract
The coupled dark energy model provides a possible approach to mitigate the coincidence problem of cosmological standard model. Here, the coupling term is assumed as $\bar{Q}=3H\xi_x\bar{\rho}_x$, which is related to the interaction rate and energy density of dark energy. We derive the background and perturbation evolution equations for several coupled models. Then, we test these models by currently available cosmic observations which include cosmic microwave background radiation from Planck 2015, baryon acoustic oscillation, type Ia supernovae, $f\sigma_8(z)$ data points from redshift-space distortions, and weak gravitational lensing. The constraint results tell us there is no evidence of interaction at 2$\sigma$ level, it is very hard to distinguish different coupled models from other ones.

Interacting dark energy in the early 2020s: a promising solution to the $H_0$ and cosmic shear tensions
An interacting dark energy model with coupling proportional to the dark energy density alleviates the H0 and S8 tensions in Planck 2018 data but is not preferred once BAO and supernova data are included.

Probing the independence within the dark sector in the fluid approximation
Current cosmological data show no statistically significant sign of an interaction between cold dark matter and dark energy, with LambdaCDM preferred, and future LSST and DESI data could constrain such a coupling at 2...

Dark Energy Is Not That Into You: Variable Couplings after DESI DR2 BAO
With DESI DR2 data, one interacting dark sector model with a time-dependent coupling shows a nonzero coupling at more than 95% CL, but Bayesian evidence still favors Lambda-CDM.

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