摘要: 利用相干态的超完备性与有序算符内的积分技术,给出若干量子玻色算符的正规排序形式.与其他方法相比,此方法在理论应用中具有简捷明了的特点.
关键词: 相干态, 算符正规排序, 有序算符内的积分
Abstract: By using the over-completeness of coherent state and the technique of integration within an ordered product of operators,we derive some new normal ordering forms of quantum operators. Compared with other methods, this method is easier and clearer in theory and application.
Key words: coherent state, normal ordering of quantum operators, technique of integration within an ordered product of operators
