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

Electric field dependence of the spin relaxation anisotropy in (111) GaAs/AlGaAs quantum wells
TL;DR: In this article, a spin density matrix model for the conduction band spin splitting including both linear and cubic terms of the Dresselhaus Hamiltonian is used which allows a quantitative description of the measured electric field dependence of the spin relaxation anisotropy.

Quantum confinement and magnetic-field effects on the electron g factor in GaAs-(Ga, Al)As cylindrical quantum dots.
TL;DR: The competition between the quantum confinement and applied magnetic field is studied, finding that in this type of heterostructure the geometrical confinement and Al concentration determine the behavior of the electron effective Landé g factor, as compared to the effect of the applied magnetic fields.

Illuminating "spin-polarized" Bloch wave-function projection from degenerate bands in decomposable centrosymmetric lattices
Pengke Li (李鹏科),Ian Appelbaum +1 more
TL;DR: In this article, the hidden spin polarization obtained by wave-function truncation is revealed by inspection of analytically solvable models and the limitations and shortcomings of this electronic structure decomposition are illuminated using arguments focused on operator commutativity and broken gauge freedom in degenerate wave function projection.

Theory of spin relaxation in laterally coupled quantum dots
TL;DR: In this article, a comprehensive quantitative analysis of the relaxation of electron spins confined in top-gated, laterally coupled semiconductor quantum dots is presented and discussed for a wide range of system parameters, such as the external magnetic field, the interdot coupling strength, and the in-plane electric field (detuning).

Magnetotransport in two-dimensional electron systems with spin-orbit interaction
TL;DR: In this paper, the spin-conserving scatterers are considered in an extension of the self-consistent Born approximation that considers the spin degree of freedom, and a modified fan chart with crossing Landau levels is calculated for homogeneous two-dimensional electron systems.

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.
