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 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 Webof the angular momentum are quantized, i.e. they can only take certain discrete values; 2) there exists a type of angular momentum that is intrinsic to a particle, even a point particle, and that cannot be put in the form r p: this is the so-called \spin angular momentum". The total angular momentum J is the sum of the orbital angular momentum ...
WebDec 8, 2024 · 7: Orbital Angular Momentum and Spin. 7.2: Spin. Pieter Kok. University of Sheffield. From classical physics we know that the orbital angular momentum of a particle is given by the cross product of its position and momentum. L = r × p or Li = ϵijkrjpk, where we used Einstein’s summation convention for the indices. WebDec 24, 2024 · Spin is quantized in the same manner as orbital angular momentum. It has been found that the magnitude of the intrinsic spin angular momentum \(S\) of an electron is given by \[S = \sqrt{s(s + 1)}\hbar, \nonumber \] where \(s\) is defined to be the spin quantum number. This is similar to the quantization of \(L\), except that the only value ...
