The article gives a solution of the classical Dirac equation for a point-like electron in a homogeneous magnetic field. The solution is obtained in the form of a power series of a characteristic small parameter. The solution is compared with the results of other scientists....

摘要: We show that the motion of a relativistic electron in a constant homogeneous magnetic field exhibits quasiperiodic behaviour (quantum revivals) and discuss the possibility of their observation.关键词: Theoretical or Mathematical/ quantum electrodynamics/ electron magnetic field relativistic electron ...
Because the two coordinates of particle's guiding center of motion in uniform magnetic field do not commute, we think it is of necessity to study adiabatic invariant of electron motion in slowly varying magnetic field in the context of quantum mechanics. By constructing the entangled state ...
(Fig.1c). The formation mechanism of the directrons is not completely understood yet and requires further experimental and theoretical investigations. Recent publications by Pikin suggested that the generation of the directrons may be due to the interaction of injected electron clouds with nematic ...
In this paper We study the properties of electron motion when a nonneutral electron beam goes through a static magnetic field. The self-electronic and magnetic fields also affects on the test electron. The Hamiltonian equations of electron motion are deduced and the Poincare surface of section and...
A relativistic orbital-drift electron-motion integral which is averaged with respect to the rotation period is derived from the general conservation law for a rotating electromagnetic field. Modifications of this integral are obtained for uniform as well as nonuniform magnetic fields in the case of ...
This additional interfacial spin torque is similar in form to the in-plane spin transfer torque, but is significantly enhanced in ultra-thin films and acts in the opposite direction to the electron flow. The combination of this diffusive spin torque and the spin-orbit torque results in skyrmion...
Because the magnetic field can be obtained using Eq. (2), we do not show its explicit form. The waveforms of the radiation fields calculated using Eq. (4) are shown in Fig. 2. As the electron velocity increases, the sinusoidal waveforms become distorted and develop kinks around the phase...
Quantized Orbital Angular Momentum Transfer and Magnetic Dichroism in the Interaction of Electron Vortices with Matter Following the very recent experimental realization of electron vortices, we consider their interaction with matter, in particular, the transfer of orbital ...
