Spin Angular Momentum

Some articles on spin, spin angular momentum, angular momentum:

Triplet State
... A spin triplet is a set of three quantum states of a system, each with total spin S = 1 (in units of ) ... The system could consist of a single elementary massive spin 1 particle such as a W or Z boson, or be some multiparticle state with total spin angular momentum of one ... In physics, spin is the angular momentum intrinsic to a body, as opposed to orbital angular momentum, which is the motion of its center of mass about an external point ...
Photon Polarization - Photons: The Connection To Quantum Mechanics - Energy, Momentum, and Angular Momentum of Photons - Angular Momentum and Spin
... Similarly for the spin angular momentum which implies that the spin angular momentum of the photon is the quantum interpretation of this expression is that the ... We can therefore think of the spin angular momentum of the photon being quantized as well as the energy ... The angular momentum of classical light has been verified ...
Spin Magnetic Moment - Calculation
... We can calculate the observable spin magnetic moment, a vector, μS, for a sub-atomic particle with charge q, mass m, and spin angular momentum (also a vector), S, via (1) where g is a dimensionless number ... The proton and neutron are composed of quarks, which have a non-zero charge and a spin of ħ/2, and this must be taken into account when calculating their g ... The proton and electron's spin magnetic moments can be calculated by setting q = +e and q = −e, respectively, where e is the elementary charge ...

Famous quotes containing the word spin:

    Words can have no single fixed meaning. Like wayward electrons, they can spin away from their initial orbit and enter a wider magnetic field. No one owns them or has a proprietary right to dictate how they will be used.
