论文摘要
我们获得了具有指数时间变化质量的自由粒子的挤压相干状态（SC）。我们根据时间无关的Fock状态的挤压和位移参数来编写这些状态。因此，我们找到了位移参数的条件，因此SC可以被视为半经典状态。我们表明，只要质量随着时间的增加而增加，就可以获得具有最小不确定性的自由粒子的相干状态（CS）。我们分析了最初在时间无关的Fock状态下到自由粒子SC的系统的过渡概率。
We obtain the squeezed coherent states (SCS) for a free particle with exponentially time-varying mass. We write these states in terms of the squeeze and displacement parameters on the time-independent Fock states. Thus, we find a condition on the displacement parameter such that the SCS can be considered semiclassical states. We show that it is possible to obtain the coherent states (CS) for a free particle with minimal uncertainty as long as the mass increases with the time. We analyze the transition probability of a system initially prepared in the time-independent Fock states to the free particle SCS.
