WebMar 6, 2024 · The spin group is used in physics to describe the symmetries of (electrically neutral, uncharged) fermions. Its complexification, Spinc, is used to describe electrically charged fermions, most notably the electron. WebApr 29, 2004 · kurious. If two spin 1 photons are put together so that the tips of their magnetic field vectors just touch one another ( the vector lines are all in the same plane), a particle results which looks the same when it is rotated through 180 degrees - a spin 2 particle.This is the spin a graviton is supposed to have.

Spin 2 Particles Explained Physics Forums
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 quantum mechanics, the other being orbital angular momentum. The orbital angular momentum operator is the quantum-mechanical … 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 (as they appear point-like), … 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 … 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 … 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 Spin has important theoretical implications and practical applications. Well-established direct applications of spin include: • Nuclear magnetic resonance (NMR) spectroscopy in chemistry; • Electron spin resonance (ESR … See more WebSpace of angular momentum states for spin s =1/2 is two-dimensional: s =1/2, m s =1/2& = ↑&, 1/2, −1/2& = ↓& General spinor state of spin can be written as linear combination, α ↑& + β ↓& =! α β ", α 2 + β 2 =1 Operators acting on spinors are 2 × 2 matrices.
