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

Quantum spin pumping with adiabatically modulated magnetic barriers
Ronald Benjamin,Colin Benjamin +1 more
TL;DR: In this paper, a quantum pump device involving magnetic barriers produced by the deposition of ferromagnetic stripes on heterostructures is investigated, which does not provide spin-polarized currents, but in the adiabatic regime, when one modulates two independent parameters of this device, spin-up and spindown electrons are driven in opposite directions, with the net result being that a finite net spin current is transported with negligible charge current.

Spin transport of electrons through quantum wires with a spatially modulated Rashba spin-orbit interaction
TL;DR: In this paper, the authors studied the ballistic transport of spin-polarized electrons through quantum wires in which the Rashba spin-orbit interaction (SOI) is spatially modulated Subband mixing, due to SOI, between the two lowest subbands is taken into account.
