TLDR
In this article, a character table for the group of the wave vector at certain points of symmetry in the Brillouin zone is given, and a possible reason for the complications which may make a simple effective mass concept invalid for some crystals of this type structure is presented.Abstract:
Character tables for the "group of the wave vector" at certain points of symmetry in the Brillouin zone are given. The additional degeneracies due to time reversal symmetry are indicated. The form of energy vs wave vector at these points of symmetry is derived. A possible reason for the complications which may make a simple effective mass concept invalid for some crystals of this type structure will be presented.read more

Electron spin relaxation in cubic GaN quantum dots: Perturbation theory and exact diagonalization study
TL;DR: In this paper, the spin relaxation time in zinc-blende GaN quantum dot was investigated for different magnetic fields, well width, and quantum dot diameter, and it was found that due to the small spin-orbit coupling in GaN, spin relaxation caused by the second-order process of the hyperfine interaction combined with the electron-phonon scattering plays much more important role than it does in the quantum dot with narrower band gap and larger spinorbit coupling, such as GaAs and InAs.

TL;DR: In this paper, the spin-orbital coupling effect on the Josephson current through a superconductor (SC) heterojunction, consisting of two s-wave superconductors and a two-dimensional electron gas (2DEG) layer between them, was studied.

TL;DR: In this paper, a 2D Kondo lattice represented by a Si-Ir-Si-Yb (SISY) surface block of the heavy-fermion material YbIr2Si2 was considered, and it was shown that the strong spin-orbit coupling with 4f moments allows finely tuning the group velocities of the strongly spin-polarized carriers in 2D itinerant states of this noncentrosymmetric system.
