The present paper shows that the nature of the polarization of charged spin-1/2 particles moving in a uniform magnetic field changes dramatically in a relatively weak transverse axisymmetric magnetic field. The direction along which the spin projection is quantized has a fixed orientation with respect to the axes of a cylindrical coordinate system and can form a substantial angle with the direction of the uniform magnetic field. The presence of spin quantization is proved both by the fact that the commutator of the Hamiltonian operator and the projection of the polarization operator in the direction of quantization is zero and by analyzing the Bargmann-Michel-Telegdi equation for this given case. Finally, the possibilities of detecting this effect and utilizing it are discussed.
The photic field in the plane divisional uniform absorbing and dispersive dielectrics is quantized by the canonical quantum theory and the classical Green's function of the system. The concrete forms of the leftwards\|traveling and rightwards\|traveling polariton and photon operators in the dielectrics and the cavity are determined by use of the identical idea of the contrast with the homogeneous media and the vacuum case, and the quantized expressions of light field in every region are given. Results show that the polariton and the photon operators can be expressed by the forms of the media noise along the propagation with phase weight, and they are closely related to the media distribution, parameters and the light frequency.
