Image-potential-induced spin-orbit interaction in one-dimensional electron systems

  title={Image-potential-induced spin-orbit interaction in one-dimensional electron systems},
  author={Yasha Gindikin and Vladimir A. Sablikov},
We study the spin-orbit interaction effects in a one-dimensional electron system that result from the image charges in a nearby metallic gate. The nontrivial property of the image-potential-induced spin-orbit interaction (iSOI) is that it directly depends on the electron density because of which a positive feedback arises between the electron density and the iSOI magnitude. As a result, the system becomes unstable against the density fluctuations under certain conditions. In addition, the iSOI…

Pair spin–orbit interaction in low-dimensional electron systems

The pair spin–orbit interaction (PSOI) is the spin–orbit component of the electron–electron interaction that originates from the Coulomb fields of the electrons. This relativistic component, which

Electron pairs bound by the spin-orbit interaction in 2D gated Rashba materials with two-band spectrum

We show that the bound electron pairs (BEPs) emerge in two-dimensional gated Rashba materials owing to the interplay of the pair spin-orbit interaction, produced by the Coulomb elds of interacting



Creation and Annihilation Operators

Creation and annihilation operators are used in many-body quantum physics because they provide a less awkward notation than symmetrized or antisymmetrized wave functions, and a convenient language
