abstract
The description of dark matter as a pressure-less fluid and of dark energy as a cosmological constant, both minimally coupled to gravity, constitutes the basis of the concordance $\Lambda\text{CDM}$ model. However, the concordance model is based on using equations of motion directly for the fluids with constraints placed on their sources, and lacks an underlying Lagrangian. In this work, we propose a Lagrangian model of two spin zero fields describing dark energy and dark matter with an interaction term between the two along with self-interactions. We study the background evolution of the fields as well as their linear perturbations, suggesting an alternative to $\Lambda$CDM with dark matter and dark energy being fundamental dynamical fields. The parameters of the model are extracted using a Bayesian inference tool based on multiple cosmological data sets which include those of Planck (with lensing), BAO, Pantheon, SH0ES, and WiggleZ. Using these data, we set constraints on the dark matter mass and the interaction strengths. Furthermore, we find that the model is able to alleviate the Hubble tension for some data sets while also resolving the $S_8$ tension.

Upper limits on dark energy-dark matter interaction from DESI DR2 in a field-theoretic analysis
A field-theoretic calculation finds that dark energy and dark matter interact only very weakly, and DESI data rule out the strong-interaction regime that would change quintessence behavior.

Cosmology of axion dark energy in supersymmetric models and constraints on high scale parameters
A two-cosine axion dark energy potential fits CMB+BAO+supernova data better than the standard one-cosine potential, while preferring a sub-Planckian decay constant and a feeble dark-matter coupling.

Sign Switching in Dark Sector Coupling Interactions as a Candidate for Resolving Cosmological Tensions
A sign-switching dark-sector coupling, fitted to CMB, DESI BAO, and supernova data, can simultaneously raise H0 and lower S8, but the preference over LambdaCDM depends on using SH0ES-calibrated supernovae.
