Models of coupled dark matter to dark energy
read the original abstract
We present three distinct types of models of dark energy in the form of a scalar field which is explicitly coupled to dark matter. Our construction draws from the pull-back formalism for fluids and generalises the fluid action to involve couplings to the scalar field. We investigate the cosmology of each class of model both at the background and linearly perturbed level. We choose a potential for the scalar field and a specific coupling function for each class of models and we compute the Cosmic Microwave Background and matter power spectra.

Phantom-divide crossing and suppressed structure growth in kinetically braided dark energy with momentum exchange
A linearly stable kinetic-braiding dark-energy model with CDM momentum exchange realizes upward phantom-divide crossing and weak CDM gravitational clustering, altering matter and CMB spectra.

Breaking the Dark Sector Degeneracy with Nonparametric Expansion--Growth Reconstruction
Joint nonparametric expansion–growth reconstruction finds no significant dark-sector interaction or dark-energy dynamics, remaining consistent with ΛCDM over 0≲z≲2.

Revisiting observational constraints on coupled exponential quintessence with energy and momentum transfers: degeneracy with massive neutrinos
Allowing the neutrino mass to vary removes the 2σ evidence for momentum transfer between dark energy and dark matter in coupled quintessence, via a degeneracy with the energy-exchange coupling.

Dark sector interactions in the $w \rightarrow -1$ limit: velocity locking in pure momentum exchange models
In momentum-exchange dark sector models, the suppression of matter clustering moves to smaller scales as w→−1 due to velocity locking, and ignoring DE perturbations erases this effect.

Dark matter-baryons elastic coupling
A new dark-matter–baryon momentum-transfer interaction suppresses small-scale clustering and is mildly preferred by data when a low-redshift S8 measurement is included.

The Status of Single Scalar Field Dark Energy
Cosmological data can constrain only a handful of EFT parameters for single-scalar dark energy; extended models show modest preference over Λ but remain underdetermined and challenged by fifth forces and screening.
