This review paper shows some methods to study electrons with spin transport properties. We focus on spin precession patterns with the influence of the spin orbital interaction (SOI) by different way to discuss the spin transport on curved system. This paper can be divided into three parts. The first part is studying the spin precession patterns in the U-shaped 1D wire by introducing a confined potential. In the second part, we introduce a non-Abelian spin–orbital gauge field to study electrons transport on a curved surface. The third part is a generalized form of part one, we study exact Hamiltonians for Rashba and cubic Dresselhaus SOIs on a curved surface. We can see a lot of significant influence of SOI on curved system in this review paper.

Spin Orbital Interaction

Based on the theory of weak localization, taking into account the mechanism of spin-orbit scattering, the patterns of change in the magnetic conductivity of films PbSnAgTe are considered. The dependences of the magnetoresistance of PbSnAgTe films in a magnetic field perpendicular to the surface of the film are studied. It is shown that for polycrystalline films on mica-muscovite substrates, the time of spin-orbital interaction depends on the composition and may change the sign of the magnetoresistance.

This paper aims at the development of 't Hooft's quantization proposal to describe composite quantum mechanical systems. In particular, we show how 't Hooft's method can be utilized to obtain from two classical Bateman oscillators a composite quantum system corresponding to a quantum isotonic oscillator. For a suitable range of parameters, the composite system can be also interpreted as a particle in an effective magnetic field interacting through a spin-orbital interaction term. In the limit of a large separation from the interaction region we can identify the irreducible subsystems with two independent quantum oscillators.

Spin Orbital Interaction

Spin-orbital interaction of light attracts much attention in nanophotonics opening new horizons for modern optical systems and devices. The photonic spin Hall effect or Imbert-Fedorov shift takes a special place among the variety of spin-orbital interaction phenomena. It exhibits as a polarization-dependent transverse light shift usually observed in specular scattering of light at interfaces with anisotropic materials. Nevertheless, the effect of the polarization mixing caused by anisotropy on the Imbert-Fedorov shift is commonly underestimated. In this work, we demonstrate that polarization mixing contribution cannot be ignored for a broad range of optical systems. In particular, we show the dominant influence of the mixing term over the standard one for the polarized optical beam incident at a quarter-wave plate within the paraxial approximation. Moreover, our study reveals a novel contribution with extraordinary polarization dependence not observable within the simplified approach. We believe that these results advance the understanding of photonic spin Hall effect and open new opportunities for spin-dependent optical phenomena.
