Query: Enhanced photon-phonon coupling via dimerization in one-dimensional
  optomechanical crystals   We show that dimerization of an optomechanical crystal lattice, which leads
to folding of the band diagram, can couple flexural mechanical modes to optical
fields within the unit cell via radiation pressure. When compared to currently
realized crystals, a substantial improvement in the coupling between photons
and phonons is found. For experimental verification, we implement a dimerized
lattice in a silicon optomechanical nanobeam cavity and measure a vacuum
coupling rate of $g_0/2\pi=1.7MHz$ between an optical resonance at $\lambda_{c}
= 1545nm$ and a mechanical resonance at 1.14GHz.
