引入Wigner函数,Weyl对应和Wigner算符相干态表象的新途径
New Approach for Introducing Wigner Function,Weyl Correspondence and the Coherent State Representation of Wigner Operator
正规乘积内积分 Wigner算符 Wigner函数 Weyl对应 integration within an ordered product(IWOP) Wigner operator Wigner function Weyl correspondence
摘要
用坐标、动量完备性的正规乘积内积分形式直接地引入了Wigner函数和Wigner算符的相干态表象,简洁地阐述了它与Weyl对应的关系。
Abstract
By using the normal ordering form of the coordinate,momentum completeness,we directly and concisely introduce the Wigner operator and then illustrate its relation with the Weyl correspondence.The coherent state representation of the Wigner operator is also neatly derived.
