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

The influence of anisotropic gate potentials on the phonon induced spin-flip rate in GaAs quantum dots
TL;DR: In this paper, anisotropic gate potential has been shown to enhance the spin-flip rate and reduce the level crossing point to a lower quantum dot radius due to the suppression of the Land$\acute{e}$ g-factor towards bulk crystal.

TL;DR: In this article, the effect of the in-plane magnetic field on spin polarization in the presence of the Dresselhaus spin-orbit effect was theoretically studied, and it was shown that the large spin polarization can be achieved in such a nanostructure due to the effects of both the DSO term and the in plane magnetic field, but the latter plays a main role in tunneling process.
