Lotte kann sich durchsetzen, aber Bullerjahn darf wenigstens d…. This gives an algebraic relation involving K and some or all of the 44 unknown matrix elements. Different rotations of the system lead to different algebraic relations, and it turns out that there is enough information to figure out all of the matrix elements in this way.

In practice, when working through this math, we usually apply angular momentum operators to the states, rather than rotating the states.

But this is fundamentally the same thing, because of the close mathematical relation between rotations and angular momentum operators.

To state these observations more precisely and to prove them, it helps to invoke the mathematics of representation theory. For example, the set of all possible 4d orbitals i.

Rotating the system transforms these states into each other, so this is an example of a "group representation", in this case, the 5-dimensional irreducible representation "irrep" of the rotation group SU 2 or SO 3 , also called the "spin-2 representation".

Similarly, the 2p quantum states form a 3-dimensional irrep called "spin-1" , and the components of the position operator also form the 3-dimensional "spin-1" irrep.

It turns out that these are transformed by rotations according to the direct product of those three representations, i.

This direct product, a dimensional representation of SU 2 , is not an irreducible representation , instead it is the direct sum of a spin-4 representation, two spin-3 representations, three spin-2 representations, two spin-1 representations, and a spin-0 i.

The nonzero matrix elements can only come from the spin-0 subspace. The Wigner—Eckart theorem works because the direct product decomposition contains one and only one spin-0 subspace, which implies that all the matrix elements are determined by a single scale factor.

The results of this calculation are the Clebsch—Gordan coefficients. The key qualitative aspect of the Clebsch—Gordan decomposition that makes the argument work is that in the decomposition of the tensor product of two irreducible representations, each irreducible representation occurs only once.

This allows Schur's lemma to be used. Starting with the definition of a spherical tensor operator , we have. This recursion relation for the matrix elements closely resembles that of the Clebsch—Gordan coefficient.

We therefore have two sets of linear homogeneous equations:. It is not possible to exactly solve for x c. We can only say that the ratios are equal, that is.

There are different conventions for the reduced matrix elements. One convention, used by Racah [5] and Wigner, [6] includes an additional phase and normalization factor,.

With this choice of normalization, the reduced matrix element satisfies the relation:. Another convention for reduced matrix elements is that of Sakurai's Modern Quantum Mechanics :.

This matrix element is the expectation value of a Cartesian operator in a spherically symmetric hydrogen-atom-eigenstate basis , which is a nontrivial problem.

However, the Wigner—Eckart theorem simplifies the problem. In fact, we could obtain the solution quickly using parity , although a slightly longer route will be taken.

We know that x is one component of r , which is a vector. In fact, it can be shown that. From Wikipedia, the free encyclopedia. The name derives from physicists Eugene Wigner and Carl Eckart , who developed the formalism as a link between the symmetry transformation groups of space applied to the Schrödinger equations and the laws of conservation of energy, momentum, and angular momentum.

Mathematically, the Wigner—Eckart theorem is generally stated in the following way. The Wigner—Eckart theorem states indeed that operating with a spherical tensor operator of rank k on an angular momentum eigenstate is like adding a state with angular momentum k to the state.

The matrix element one finds for the spherical tensor operator is proportional to a Clebsch—Gordan coefficient, which arises when considering adding two angular momenta.

When stated another way, one can say that the Wigner—Eckart theorem is a theorem that tells how vector operators behave in a subspace.

Within a given subspace, a component of a vector operator will behave in a way proportional to the same component of the angular momentum operator.

This definition is given in the book Quantum Mechanics by Cohen—Tannoudji, Diu and Laloe. Let's say we want to calculate transition dipole moments for an electron transition from a 4d to a 2p orbital of a hydrogen atom, i.

The Wigner—Eckart theorem allows one to obtain the same information after evaluating just one of those 45 integrals any of them can be used, as long as it is nonzero.

Then the other 44 integrals can be inferred from that first one—without the need to write down any wavefunctions or evaluate any integrals—with the help of Clebsch—Gordan coefficients , which can be easily looked up in a table or computed by hand or computer.

The Wigner—Eckart theorem works because all 45 of these different calculations are related to each other by rotations. Similarly, if an electron is in one of the 4d orbitals, rotating the system will move it into a different 4d orbital.

Finally, an analogous statement is true for the position operator: when the system is rotated, the three different components of the position operator are effectively interchanged or mixed.

This gives an algebraic relation involving K and some or all of the 44 unknown matrix elements. Different rotations of the system lead to different algebraic relations, and it turns out that there is enough information to figure out all of the matrix elements in this way.
