Growing Matter
read the original abstract
We investigate quintessence cosmologies with a matter component consisting of particles with an increasing mass. While negligible in early cosmology, the appearance of a growing matter component has stopped the evolution of the cosmon field at a redshift around six. In turn, this has triggered the accelerated expansion of the Universe. We propose to associate growing matter with neutrinos. Then the presently observed dark energy density and its equation of state are determined by the neutrino mass.

Mass-Varying Dark Matter Induced Scalarization and Scalar Clouds around Black Holes
Scalar clouds around black holes in mass-varying dark matter halos exist only for quantized scalar-dark matter couplings set by halo parameters such as compactness.

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.

Mass-Varying Neutrinos from an Inverse Symmetron
An inverse symmetron model for mass-varying neutrinos tames linear instabilities, suppresses matter power spectrum, and may address the Hubble tension via early dark energy around recombination.
