【Abstract】 The coupling between the motion of the center-of-mass and the internal transition in a trapped ion, driven by a classical laser beam, is discussed. Without using Lamb-Dicke limit, the precise analytical solution of wave function is deduced in this model. The numerical simulations show that, under proper parameters chosen, the apparent squeezing occurs in both the vibration and the spin variables for the trapped ion.更多还原
