Vainshtein screening in Horndeski theories nonminimally and kinetically
  coupled to ordinary matter
  We study the Vainshtein screening mechanism in Horndeski theories in the
presence of a scalar field $\phi$ nonminimally and kinetically coupled to
ordinary matter field. A general interacting Lagrangian describing this
coupling is characterized by energy transfer $f_1$ and momentum exchange $f_2$.
For a spherically symmetric configurations on top of the cosmological
background, we investigate the static perturbations in linear and nonlinear
regimes with respect to the scalar field perturbation. In the former regime,
the PPN parameter generally deviates from unity as long as the matter coupling
or $G_{4,\phi}$ exists. On the other hand, in the latter regime, we show that
the nonlinear self interaction term of scalar field successfully activates the
Vainshtein mechanism even in the presence of the couplings $f_1$ and $f_2$. The
gravitational potentials recover the Newtonian behavior deep inside the
Vainshtein radius. The bounds on coupling terms not to substantially change the
Vainshtein radius are also given.
