An interesting dynamical model for dark energy which does not require extremely light scalar fields such as quintessence, and at the same time explains the (near-) coincidence between the neutrino and dark energy densities is the model of dark energy coupled to mass varying neutrinos (MaVaNs). Despite the attractions of this model, we show that, generically, this model contains a catastrophic instability which occurs when neutrinos become non-relativistic. As a result of this instability, as neutrinos become non-relativistic, they condense into neutrino nuggets which redshift away similar to cold dark matter, and thus cease to act as dark energy. Any stable MaVaNs dark energy model is extremely contrived, and is virtually indistinguishable from a cosmological constant.

Dark Energy and Neutrino Flavor from the Weak Axion
The dark-energy scale is predicted from neutrino masses and PMNS mixing: the weak-axion Coleman-Weinberg potential lands at 1-4 meV for current neutrino data.

The cosmology of long range Yukawa interactions in general backgrounds
Generalization of scalar-fermion Yukawa systems in constant-EOS cosmologies identifies scaling regime with constant energy density ratio from approximate scale invariance and asymptotic regime recovering bare mass.

Probing Long-Range Forces Between Neutrinos with Cosmic Structures
Neutrino long-range forces stronger than gravity would make the cosmic neutrino background collapse into bound states, and existing matter power spectrum and reionization data now exclude a band of couplings for force...
