Resumen:
We analyze the stability and dynamics of an ion chain confined inside a
high-finesse optical resonator. When the dipolar transition of the ions
strongly couples to one cavity mode, the mechanical effects of light
modify the chain properties close to a structural transition. We focus
on the linear chain close to the zigzag instability and show that linear
and zigzag arrays are bistable for certain strengths of the laser
pumping the cavity. For these regimes the chain is cooled into one of
the configurations by cavity-enhanced photon scattering. The excitations
of these structures mix photonic and vibrational fluctuations, which
can be entangled at steady state. These features are signaled by
Fano-like resonances in the spectrum of light at the cavity output.
