Corrections to Wigner–Eckart Relations by Spontaneous Symmetry Breaking
The matrix elements of operators transforming as irreducible representations of an unbroken symmetry group <i>G</i> are governed by the well-known Wigner–Eckart relations. In the case of infinite-dimensional systems, with <i>G</i> spontaneously broken, we prove that the corre...
