【Abstract】 The quadrature squeezing properties of an ion, trapped in the harmonic potential, interacting with a standing-wave laser field are studied under the condition of p-quantum resonance. The effects of the parameter p, the Lamb-Dicke constant η and the position of the ion in the standing-wave field on the vibrational squeezing are revealed by numerical calculation and theoretical analysis. The results show that a large Lamb-Dicke parameters is not conducive to squeezing, while the multi-quantum resonance contributes to the squeezing effect. When the ion center moves from the antinode to the node of the standing-wave laser field, the variations of the width and the occurring time of the squeezing zone are opposite for odd and even p’s.更多还原
