The Wigner-Eckart theorem states that if we have a spherical tensor Tkq in the space spanned by the wave functions |JM>, then the matrix elements are $$=\\;\\quad (Rose,\\;1957)\\;or\\;= {{( - 1)}^{J' - M'}}(\\begin{array}{*{20}{c}}{L'} & k & L \\\{ - ...

The Wigner-Eckart Theorem in Cosmology Total-angular-momentum (TAM) waves provide a set of basis functions for scalar, vector, and tensor fields that can be used in place of plane waves and that reflect the rotational symmetry of the spherical sky. Here we discuss three-point... L Dai,D...
The Wigner-Eckart theorem dictates that the expectation value, assuming statistical isotropy, of the product of three TAM waves is the product of a Clebsch-Gordan coefficient (or Wigner-3j symbol) times a function only of the total-angular-momentum quantum numbers. Here we show how this works,...
In Section V.3 tensor operators are introduced and the Wigner-Eckart theorem for the rotation group is stated without derivation. In Section V.4 a new observable, parity, is introduced. Parity is then applied to discuss the spectrum of diatomic symmetric-top molecules. In an Appendix to ...
We prove Wigner-Eckart theorem for the irreducible tensor operators for arbitrary Hopf algebras, provided that tensor product of their irreducible representation is completely reducible. The proof is based on the properties of the irreducible representat
