In quantum mechanics, the angular momentum operator is one of several related operators analogous to classical angular momentum. The angular momentum operator plays a central role in the theory of atomic and molecular physics and other quantum problems involving rotational symmetry. Such an … See more In quantum mechanics, angular momentum can refer to one of three different, but related things. Orbital angular momentum The classical definition of angular momentum See more In quantum mechanics, angular momentum is quantized – that is, it cannot vary continuously, but only in "quantum leaps" between … See more The Hamiltonian H represents the energy and dynamics of the system. In a spherically symmetric situation, the Hamiltonian is … 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 Commutation relations between components The orbital angular momentum operator is a vector operator, … See more The most general and fundamental definition of angular momentum is as the generator of rotations. More specifically, let $${\displaystyle R({\hat {n}},\phi )}$$ be a rotation operator, which rotates any quantum state about axis $${\displaystyle {\hat {n}}}$$ by … See more Angular momentum operators usually occur when solving a problem with spherical symmetry in spherical coordinates. The angular momentum in the spatial representation is In spherical coordinates the angular part of the See more Webangular momentum in relation to the group of rotations. Just as linear momentum is related to the translation group, angular momentum operators are generators of rotations. The goal is to present the basics in 5 lectures focusing on ... The commutation relations are a property of the group, not just a particular representation. The collection ...

WebMay 14, 2015 · May 14, 2015 at 15:25. From the perspective of Lie algebras, the commutation relations are fundamental; any such set of operators that satisfy these relations are a realization of that particular Lie algebra. We can then take a set of operators acting on some vector space (such as L z = − i ℏ ( x ∂ y − y ∂ x) and so forth, acting on ...
