“…BMT equation successfully confirmed the results of experiments on precision determination of the anomalous magnetic moment of an electron [13,14], muon [15] and also the masses of a number of heavy elementary particles [16]. As it turned out well to explain the experimentally observed effect of radiative self-polarization of electrons [17,18] within the frameworks of the quasiclassical spin theory as well as the Dirac quantum theory. Moreover, it was found that even purely quantum effect such as spin-flip radiation has classical description [19].…”

The motion of a magnetic spin particle in electromagnetic fields is considered on the basis of general principles of the classical relativistic theory. Alternative approaches in derivation of the equations of charge motion and spin precession, the problem of noncollinearity of the momentum and velocity of a particle with spin, the origin and the meaning of Thomas precession in dynamics of the spin particle are also considered. The correspondence principle in the spin theory is discussed.

“…On this basis, we predict a mechanism of the electromagnetic radiation by an electron moving in matter which we term the "spin light of electron in matter" (SLe). Note that the similar term ("spin light of electron in magnetic field") was used previously for the magnetic moment dependent contribution to the radiation of an electron in a magnetic field [32]. The SLe photon energy, obtained from the energy conservation law, is given by…”

Abstract. Motivated by the need of elaboration of the quantum theory of the spin light of neutrino in matter (SLν), we have studied in more detail the exact solutions of the Dirac equation for neutrinos moving in the background matter. These exact neutrino wave functions form a basis for a rather powerful method of investigation of different neutrino processes in matter, which is similar to the Furry representation of quantum electrodynamics in external fields. Within this method we also derive the corresponding Dirac equation for an electron moving in matter and consider the electromagnetic radiation ("spin light of electron in matter", SLe) that can be emitted by the electron in this case.

“…Radiative effects in relativistic beams in accelerators is mainly a classical phenomenon [2]: the leading terms in expansions of the radiation probability and power as power series in the parameter χ (χ ~ 10 -5 -10 -4 ) are explained by the classical orbital motion of a point source. The leading spin corrections to classical expressions are linear in χ (in relative units) and are responsible for the spin light effect produced by quantum transitions without spin flip [3,4].…”

Spin radiative effects in a one-particle sector of QED have a dual nature and can be understood with the Frenkel classical rotating-electron model. In the region of parameters under study ≫ 1 ( = 1 + /m 2 ) and χ ≪ 1 (χ = /m 3 ), the imaginary part of the mass shift and radiation power contain two types of spin contributions. The contributions of the first type are related to the intrinsic magnetic moment of a fermion representing an additional source of electromagnetic radiation. The contributions of the second type have the opposite sign and are caused by a small change in the electron acceleration appearing due to the Frenkel addition to the particle mass. Contributions of the second type dominate, which explains the "wrong" sign of total spin corrections. We show that not only the sign but also the values of coefficients can be explained with specified accuracy using classical electrodynamics if corrections to the mass shift (action) and radiation power are calculated in canonical variables, i.e., for fixed velocity and momentum values, respectively. The results can be treated as a demonstration of the correspondence principle in the field of radiative spin effects, in addition to correspondence between classical and quantum theories at the tree (in the external filed) level. For a e ≡ (g -2)/2 ≲ χ ≪ 1, equations of the Frenkel model lead to generalization of the system of Lorentz-BMT (Bargmann-Michel-Telegdi) equations taking into account the Frenkel addition to mass. Some features of experimental observations of the spin light are discussed.
