Tunable polarization in beam-splitter based on 2D topological insulators
Dietrich G. Rothe, Ewelina M. Hankiewicz
The typical bulk model describing 2D topological insulators (TI) consists of two types of spin-orbit terms, the so-called Dirac term which induces out-of plane spin polarization an…
Spin-dependent thermoelectric transport in HgTe/CdTe quantum wells
D. G. Rothe, E. M. Hankiewicz, B. Trauzettel +1
We analyze thermally induced spin and charge transport in HgTe/CdTe quantum wells on the basis of the numerical non-equilibrium Green's function technique in the linear response re…
All-electric qubit control in heavy hole quantum dots via non-Abelian geometric phases
Jan C. Budich, Dietrich G. Rothe, Ewelina M. Hankiewicz +1
We demonstrate how non-Abelian geometric phases can be used to universally process a spin qubit in heavy hole quantum dots in the absence of magnetic fields. A time dependent elect…
Fingerprint of Different Spin-Orbit Terms for Spin Transport in HgTe Quantum Wells
D. G. Rothe, R. W. Reinthaler, C. -X. Liu +3
Using theory, we derive an effective four band model describing the physics of the typical two-dimensional topological insulator (HgTe/CdTe quantum well)…
