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

Discovery of a novel linear-in-k spin splitting for holes in the 2D GaAs/AlAs system.
TL;DR: A large linear scaling of hole states in 2D emerges from coupling of hole bands that would be unsuspected by the standard model that judges coupling by energy proximity, implying a different understanding of hole physics in low dimensions.

Effect of Time-Reversal Symmetry on Energy Bands of Crystals
TL;DR: In this paper, a criterion is developed to facilitate calculation of when and how such additional degeneracy will occur, and the consequences of the reality of the Hamiltonian are tabulated for a number of cases.
