Derivation of quantized angular momentum
WebMay 10, 2010 · Spin is a Casimir invariant of the Poincare group, namely the angular momentum in the rest frame of the particle. This does not preclude that spin is a purely classical quantity. E.g. the usual angular momentum L of a composite particle like a hydrogen atom or a neutron is a really a spin according to this definition.

In a spherically symmetric situation, the Hamiltonian is invariant under rotations: To summarize, if H is rotationally-invariant (spherically symmetric), then total angular momentum J is … See more Angular momentum operators usually occur when solving a problem with spherical symmetry in spherical coordinates. The angular … See more Commutation relations between components The orbital angular momentum operator is a vector operator, meaning it can be written in terms of … See more The most general and fundamental definition of angular momentum is as the generator of rotations. More specifically, let See more Often, two or more sorts of angular momentum interact with each other, so that angular momentum can transfer from one to the other. For example, in spin–orbit coupling, angular momentum can transfer between L and S, but only the total J = L + S is conserved. In … See more
