WebMay 27, 2024 · 3. I started a little project in python, under the assumption that it would be easy to find a routine for numerically computing Clebsch-Gordan coefficients in some library such as scipy. When it came time to do it, I actually found that it was difficult to locate an appropriate library. Scipy doesn't seem to have it.

In physics, the Clebsch–Gordan (CG) coefficients are numbers that arise in angular momentum coupling in quantum mechanics. They appear as the expansion coefficients of total angular momentum eigenstates in an uncoupled tensor product basis. In more mathematical terms, the CG coefficients are used in … See more Angular momentum operators are self-adjoint operators jx, jy, and jz that satisfy the commutation relations By developing this concept further, one can define another operator j as the inner product of … See more The recursion relations were discovered by physicist Giulio Racah from the Hebrew University of Jerusalem in 1941. Applying the total angular momentum raising and lowering operators (and is therefore … See more For J = 0 the Clebsch–Gordan coefficients are given by For J = j1 + j2 and M = J we have For j1 = j2 = J / 2 and m1 = −m2 we have For j1 = j2 = m1 = −m2 we have For j2 = 1, m2 = 0 we have For j2 = 1/2 we have See more It can be shown from the above definitions that j commutes with jx, jy, and jz: When two Hermitian operators commute, a common set of eigenstates exists.
