Scheme to measure squeezing and phase properties of a harmonic oscillator
We propose a simple scheme to measure squeezing and phase properties of a
harmonic oscillator. We treat in particular the case of a the field, but the
scheme may be easily realized in ion traps. It is based on integral transforms
of measured atomic properties as atoms exit a cavity. We show that by measuring
atomic polarizations it is possible, after a given integration, to measure
several properties of the field.Comment: Presented at XI Central European Workshop on Quantum Optics, Trieste,

Exact solution of the ion-laser interaction in all regimes
We show that in the trapped ion-laser interaction all the regimes may be
considered analytically. We may solve not only for different laser intensities,
but also away from resonance and from the Lamb-Dicke regime. It is found a
dispersive Hamiltonian for the high intensity regime, that, being diagonal, its
evolution operator may be easily calculated
