托雷斯-维加和弗雷德里克的理论(1993 J. Chem. Phys. 98 3103),Harriman(1994 J.Chem.Phys.100 3651)和Ban等人的方法制备。(1998J.Math.Phys.391744),其中相空间点(p,q)的作为组态变量来制定量子力学被认为是从一类量子化方案的立场,带算子的相空间函数这些方案与Torres-Vega和Fredrick给出的理论之间的联系(1993 J. Chem. Phys. 98 3103),Harriman(1994 J.Chem.Phys.100 3651),Dirac 1930年《量子力学原理》(The Principles of Quantum Mechanics)牛津大学出版社)),Moller,Jorgensen and Torres-Vega(1997 J.Chem.Phys.106 7228),Klauder和Skagerlovel(1985相干态:在物理学和数学物理学中的应用(新加坡:World Scientific)),Li,Wei and Lu(2004 Phys.Rev.A70 022105),Ban(1998 J.Math.Phys.39 1744)中的方法,利用增广波函数<$(λ)σ(p,q; t),其中λ = 0对应于Wigner和Weyl的序.对于这种情况下,我们使用这些功能来定义一个家庭的积极运营商值的措施的相位角的谐振子。
Theories of Torres-Vega and Fredrick (1993 J. Chem. Phys. 98 3103), Harriman (1994 J. Chem. Phys. 100 3651) and of Ban (1998 J. Math. Phys. 39 1744), in which phase space points (p, q) are used as configurational variables to formulate quantum mechanics are considered from the standpoint of a class of quantization schemes associating phase space functions with operators. The connection between these schemes and the theories given in Torres-Vega and Fredrick (1993 J. Chem. Phys. 98 3103), Harriman (1994 J. Chem. Phys. 100 3651), Dirac (1930 The Principles of Quantum Mechanics (Oxford: Oxford University Press)), Moller, Jorgensen and Torres-Vega (1997 J. Chem. Phys. 106 7228), Klauder and Skagerstam (1985 Coherent States: Applications in Physics and Mathematical Physics (Singapore: World Scientific)), Li, Wei and Lu (2004 Phys. Rev. A 70 022105), Ban (1998 J. Math. Phys. 39 1744) is made by means of augmented wavefunctions ψ(λ)σ(p, q; t), where λ = 0 corresponds to the ordering of Wigner and Weyl. For that case we use these functions to define a family of positive operator-valued measures for the phase angle of an harmonic oscillator.
