Linear Perturbations in a coupled cosmon-bolon cosmology
Joschka Beyer
We investigate linear perturbations in the recently proposed cosmon-bolon model of coupled scalar field dark matter and quintessence. We provide an analytical mechanism to average…

Adiabatic perturbations in coupled scalar field cosmologies
Joschka Beyer
We present a comprehensive and gauge invariant treatment of perturbations around cosmological scaling solutions for two canonical scalar fields coupled through a common potential i…

Small scale structures in coupled scalar field dark matter
Joschka Beyer, Christof Wetterich
We investigate structure formation for ultralight scalar field dark matter coupled to quintessence, in particular the cosmon-bolon system. The linear power spectrum is computed by…
