Spin vector wiki
Spin is described mathematically as a vector for some particles such as photons, and as spinors and bispinors for other particles such as electrons. Spinors and bispinors behave similarly to vectors: they have definite magnitudes and change under rotations; however, they use an unconventional "direction". See more Spin is a conserved quantity carried by elementary particles, and thus by composite particles (hadrons) and atomic nuclei. Spin is one of two types of angular momentum in … See more As the name suggests, spin was originally conceived as the rotation of a particle around some axis. While the question of whether elementary particles actually rotate is ambiguous … See more In ordinary materials, the magnetic dipole moments of individual atoms produce magnetic fields that cancel one another, because each dipole points in a random direction, with the … See more Operator Spin obeys commutation relations analogous to those of the orbital angular momentum See more Particles with spin can possess a magnetic dipole moment, just like a rotating electrically charged body in classical electrodynamics. These magnetic moments can be … See more Spin projection quantum number and multiplicity In classical mechanics, the angular momentum of a particle possesses not only a magnitude … See more In tables of the spin quantum number s for nuclei or particles, the spin is often followed by a "+" or "−". This refers to the parity with "+" for even parity (wave function unchanged … See more WebSpin is an angular momentum, so in the rest frame it is a 3-dimensional vector, or 4-dimensional vector with zero time component: v → = ( v 1, v 2, v 3) Each 3D vector can be associated with a 2x2 matrix by the following rule: V = v 3 v 1 − i v 2 v 1 + i v 2 − v 3
