Resumen:
We consider an optomechanical system composed of a trapped ion dispersively coupled to a single mode of apumped optical cavity.We focus on a parameter range for which the semiclassical description predicts two clearlydistinct equilibrium configurations in the limits of small and large photon pumping, while a bistable regime isfound for intermediate pumping. This semiclassical description, however, is not valid in close proximity to thesystem transitions or when the mean photon number is low. Here, we provide a numerical analysis of the fullyquantum state in the few-photon regime, exploring the features of the asymptotic state across the transition andanalyzing possible markers of semiclassical bistability. We find an increase in the entropy of the system and ofthe entanglement in the transition region but no clear signatures of metastability in the spectrum of the evolution.
