Engineering phonon-photon interactions with a driven trapped ion in a
cavity
R. L. Rodrigues, M. H. Y. Moussa, C. J. Villas-Boas
abstract: We show how to generate quadratic and bi-quadratic phonon-photon interactions
through a driven three-level ion inside a cavity. With such a system it is
possible to squeeze the cavity-field state, the ion motional state or even the
entangled phonon-photon state. We present a detailed analysis of the
cavity-field squeezing process, distinguishing three different regimes of this
amplification mechanism: the subcritical, critical, and supercritical regimes,
which depend, apart from the coupling parameters, on the excitation of the
vibrational state. As an application of the engineered Hamiltonians, we show
how to implement a Fock-state filter for the vibrational mode. New aspects of
the technique of adiabatic elimination emerge in this analysis.
