我们讨论一族准分布(Agarwal和Wolf的s-序维格纳函数[Phys.Rev.D2,2161(1970); Phys.Rev.D2,2187(1970); Phys.Rev.D2,2206(1970)])及其与薛定谔方程的所谓相空间表示的联系。事实证明,虽然维格纳函数满足相空间中的薛定谔方程,但它们有完全不同的解释。
We discuss a family of quasidistributions (s-ordered Wigner functions of Agarwal and Wolf [Phys. Rev. D 2, 2161 (1970); Phys. Rev. D 2, 2187 (1970); Phys. Rev. D 2, 2206 (1970)]) and its connection to the so-called phase space representation of the Schrodinger equation. It turns out that although Wigner functions satisfy the Schrodinger equation in phase space, they have a completely different interpretation.
