For each spherical harmonic, a corresponding traceless symmetric tensor is … WebVector spherical harmonics are developed from coupling L units of orbital angular momentum and one unit of spin angular momentum. •. An extension, coupling L units of orbital angular momentum and two units of spin angular momentum to form tensor spherical harmonics, is presented by Mathews. 4. •.
WebMay 3, 2024 · The reason is this: spherical harmonics are the eigen functions of the angular momentum operator (in the quantum view), meaning they are the standing wave solutions to waves on a sphere (in the classical view), and those are easy to visualize. Meanwhile, spherical tensors (not quantum operators, just regular complex linear combinations of ... WebB. Spherical Tensors The fact that Cartesian tensors are reducible prompts us to seek out an irreducible set of tensors. A useful set of these are the spherical tensors. 1. Spherical …
