Features due to spin-orbit coupling in the optical conductivity of single-layer graphene
P. Ingenhoven, J. Z. Bernad, U. Zuelicke +1
We have calculated the optical conductivity of a disorder-free single graphene sheet in the presence of spin-orbit coupling, using the Kubo formalism. Both intrinsic and structural…
Observation of orientation- and -dependent Zeeman spin-splitting in hole quantum wires on (100)-oriented AlGaAs/GaAs heterostructures
J. C. H. Chen, O. Klochan, A. P. Micolich +6
We study the Zeeman spin-splitting in hole quantum wires oriented along the and crystallographic axes of a high mobility undoped (100)-oriented AlGaAs/GaAs he…
Time reversal of pseudo-spin 1/2 degrees of freedom
R. Winkler, U. Zülicke
We show that pseudo-spin 1/2 degrees of freedom can be categorized in two types according to their behavior under time reversal. One type exhibits the properties of ordinary spin w…
Effects of a continuous quantum measurement on the electric conductivity: Application to graphene
J. Z. Bernad, M. Jaaskelainen, U. Zuelicke
We use linear-response theory to evaluate the frequency-dependent conductivity of a system subject to a continuous quantum measurement of the current. Application of this formalism…
Anomalous Spin-Related Quantum Phase in Mesoscopic Hole Rings
M. Jaaskelainen, U. Zuelicke
We have obtained numerically exact results for the spin-related geometric quantum phases that arise in p-type semiconductor ring structures. The interplay between gate-controllable…
