We investigate the dynamics of a mechanical resonator in which is embedded an
ensemble of two-level systems interacting with an optical cavity field. We show
that this hybrid approach to optomechanics allows for enhanced effective
interactions between the mechanics and the cavity field, leading for instance
to ground state cooling of the mechanics, even in regimes, like the unresolved
sideband regime, in which standard radiation pressure cooling would be
inefficient.Comment: 9 pages, 4 figure
