Spin is an intrinsic form of angular momentum carried by elementary particles, and thus by composite particles such as hadrons, atomic nuclei, and atoms. [1] [2]: 183–184 Spin is quantized, and accurate models for the interaction with spin require relativistic quantum mechanics or quantum field theory.
Kurt Cobain, Courtney Love, and their daughter Frances on Spin, December 1992 [2]. Spin was established in 1985 by Bob Guccione, Jr. [3] [4] In August 1987, the publisher announced it would stop publishing Spin, [5] but Guccione Jr. retained control of the magazine [6] and partnered with former MTV president David H. Horowitz to quickly revive the magazine. [5]
Spin is the fundamental property that distinguishes the two types of elementary particles: fermions, with half-integer spins; and bosons, with integer spins. Photons, which are the quanta of light, have been long recognized as spin-1 gauge bosons. The polarization of the light is commonly accepted as its “intrinsic” spin degree of freedom ...
Spin- 1 / 2 particles can have a permanent magnetic moment along the direction of their spin, and this magnetic moment gives rise to electromagnetic interactions that depend on the spin. One such effect that was important in the discovery of spin is the Zeeman effect , the splitting of a spectral line into several components in the ...
SPiN is an international chain of franchised table tennis clubs and bars. The company was founded in 2009 by Jonathan Bricklin, Andrew Gordon, Franck Raharinosy, [ 1 ] [ 2 ] and Wally Green . [ 3 ] [ 4 ]
A spin model is a mathematical model used in physics primarily to explain magnetism. Spin models may either be classical or quantum mechanical in nature. Spin models have been studied in quantum field theory as examples of integrable models. Spin models are also used in quantum information theory and computability theory in theoretical computer ...
A unit with spin number n is called an n-unit and has angular momentum nħ/2, where ħ is the reduced Planck constant. For bosons, such as photons and gluons, n is an even number. For fermions, such as electrons and quarks, n is odd. Given any closed spin network, a non-negative integer can be calculated which is called the norm of the
A simplified illustration of the spin chain model. The spin of the ith site can interact with the spins from the i - 1 and i + 1 sites. A spin chain is a type of model in statistical physics. Spin chains were originally formulated to model magnetic systems, which typically consist of particles with magnetic spin located at fixed sites on a lattice.
