摘要：
We study the evolution of coherent and Schrodinger cat states in radio-frequency traps, which were used to bound Hg+ ions. The quantum confinement is determined by evaluating the expectation values and dispersions of thr position and momentum operators, together with the probability densities in coordinate and momenta representations. Also the Wigner functions associated to this nonstationary quantum system, a parametric oscillator, are constructed.
