WebMar 4, 2024 · Assume that the eigenvalues of L 2 and Lz are unknown, and call them λ and μ. We introduce two new operators, the raising and lowering operators L + = Lx + iLy and L − = Lx − iLy. The commutator with Lz is [Lz, L ±] = ± ℏL ± (while they of course commute with L 2 ). Now consider the function f ± = L ± f, where f is an eigenfunction of L 2 and Lz:
In quantum mechanics, the angular momentum operator is one of several related operators analogous to classical angular momentum.
