WebWe demonstrate that the Wigner function of a pure quantum state is a wave function in a specially tuned Dirac bra-ket formalism and argue that the Wigner function is in fact a probability amplitude for the quantum particle to be at a certain point of the classical phase space. Additionally, we establish that in the classical limit, the Wigner function … WebMar 24, 2009 · The Clebsch-Gordan coefficient will be evaluated via its relation to Wigner 3- j symbols: j 1 m 1 j 2 m 2 j 3 m 3 = ( − 1) j 1 − j 2 + m 3 2 j 3 + 1 ( j 1 j 2 j 3 m 1 m 2 − m 3) See also the documentation on Wigner 3- j symbols which exhibit much higher symmetry relations than the Clebsch-Gordan coefficient.
