| 摘 要： | 引入了压缩附加光子相干态|α,m,ξ〉=S(ξ)a+m|α〉(未归一化),其中,|α〉为相干态,m为整数,S(ξ)为压缩算子。研究了这个态的数学性质和物理特性——处于该态的场的相压缩性质。结果表明,随着压缩参数r的增大,场的直角分量x被压缩地越多。

| Abstract: | This paper introduces the squeezed photon-added coherent states defined by |α,m,ξ〉=S(ξ)a+m|α〉up to a normalization constant,where |α〉is a coherent state,m an integer and S(ξ) a squeezing operator.It studies the mathematical and physical properties of such states.Phase squeezing character of the fields in such states is demonstrated.The conclusion shows that the more field quadrature x is squeezed,the larger squeezing parameter becomes. |
