Spin-3/2 physics of semiconductor hole nanowires: Valence-band mixing and tunable interplay between bulk-material and orbital bound-state spin splittings
D. Csontos, P. Brusheim, U. Zuelicke +1
We present a detailed theoretical study of the electronic spectrum and Zeeman splitting in hole quantum wires. The spin-3/2 character of the topmost bulk-valence-band states result…
Catching the zitterbewegung
P. Brusheim, H. Q. Xu
We demonstrate how the zitterbewegung charge oscillations can be detected through a charge conductance measurement in a three-terminal junction. By tuning the spin-orbit interactio…
Lande-like formula for the g factors of hole-nanowire subband edges
D. Csontos, U. Zülicke, P. Brusheim +1
We have analyzed theoretically the Zeeman splitting of hole-quantum-wire subband edges. As is typical for any bound state, their g factor depends on both an intrinsic g factor of t…
Fano effect in a ring-dot system with tunable coupling
A. Fuhrer, P. Brusheim, T. Ihn +4
Transport measurements are presented on a quantum ring that is tunnel-coupled to a quantum dot. When the dot is in the Coulomb blockade regime, but strongly coupled to the open rin…
Spin Hall effect and zitterbewegung in an electron waveguide
P. Brusheim, H. Q. Xu
We study spin-resolved probability distributions for electrons in a multichannel waveguide in the presence of a spin-orbit interaction. For a spin-polarized electron injection, a z…
