Structure Formation in the Effective Field Theory of Holographic Dark
  Energy
  We investigate the structure formation in the effective field theory of the
holographic dark energy. The equation of motion for the energy contrast
$\delta_m$ of the cold dark matter is the same as the one in the general
relativity up to the leading order in the small scale limit $k\gg aH$, provided
the equation of state is Quintessence-like. Our effective field theory breaks
down while the equation of state becomes phantom-like. We propose a solution to
this problem by eliminating the scalar graviton.
