通过应用与厄米激发叠加算符相关的正交化算子,产生相干态的正交态[公式:见正文]。利用一些技巧,巧妙地处理了归一化,并讨论了正交态的非经典和非高斯性。详细推导了正交态的维格纳函数的解析表达式。数值结果表明,通过改变相互作用参数,正交态将表现出丰富的非经典和非高斯性。
An orthogonal state of coherent state is produced by applying an orthogonalizer related with Hermite-excited superposition operator [Formula: see text]. Using some technique, we cleverly deal with the normalization and discuss the nonclassical and non-Gaussian characters of the orthogonal state. The analytical expressions for the Wigner functions of the orthogonal state are derived in detail. Numerical results show that the orthogonal state will exhibit its richly nonclassical and non-Gaussian character by changing the interaction parameters.
