The Wigner-Eckart Theorem

Igal Talmi

Published Oct 6, 2017• 0 citations
Publisher

Abstract

The use of irreducible tensor operators is very convenient for systems whose eigenstates have definite values of J and M . The transformation properties of operators and wave functions, both kinds being components of irreducible tensors, allow the efficient use of geometrical properties. This leads to great simplifications in the calculation of matrix elements as we shall see in the present section.

A SIMPLE DERIVATION OF THE WIGNER-ECKART THEOREM

Huang Shi-zhong

Based on the commutation relations between the components of an irreducible tensor operator of rank k and the angular momentum operator, a simple derivation of the Wigner-Eckart theorem is presented with the aid of the properties of angular momentum operators and their eigenstates.

Some Properties of Correlation Functions of Irreducible Tensor Operators

Paul S. Hubbard

Properties of quantum-mechanical time-dependent correlation functions of pairs of irreducible tensor operators are derived from the transformation properties of the tensor operators under rotations, the assumed rotational invariance of the Hamiltonian of the system, and the Wigner-Eckart theorem. It is shown that many of the possible correlation functions are zero, and that the nonzero correlation functions can be expressed in terms of reduced matrix elements. Some examples of irreducible tensor operators which occur in applications are given, and their reduced matrix elements are calculated.

The Wigner–Eckart Theorem and Other Applications

Nadir Jeevanjee

Chapter 6 applies the material of the previous chapters to some particular topics, specifically the Wigner–Eckart theorem, selection rules, and gamma matrices and Dirac bilinears. We begin by discussing the perennially confusing concepts of vector operators and spherical tensors, and then unify them using the notion of a representation operator. We then use this framework to derive a generalized selection rule, from which the various quantum-mechanical selection rules can be derived, and we also discuss the Wigner–Eckart theorem. We conclude by showing that Dirac’s famous gamma matrices can be understood in terms of representation operators, which then immediately gives the transformation properties of the ‘Dirac bilinears’ of QED.
