Dark Energy and Dark Matter from Yang-Mills Condensate and the
  Peccei-Quinn mechanism
  We analyze a model of cold axion Dark Matter weakly coupled with a dark gluon
condensate, reproducing Dark Energy. We first review how to recover the Dark
Energy behavior using the functional renormalization group approach, and ground
our study on the properties of the effective Lagrangian, to be determined
non-perturbatively. Then, within the context of $G_{SM}\times SU(2)_{D}\times
U(1)_{PQ}$, we consider YMC interactions with QCD axions. We predict a transfer
of Dark Energy density into Dark Matter density in a cosmological time that can
be tested in the next generation of experiments dedicated to Dark Energy
measures.
