Anomalous conductance steps in three-dimensional topological insulator HgTe-based quantum point contacts
Elisabeth Richter, Michael Barth, Dmitriy A. Kozlov +8
We explore electrical transport through a point contact in strained HgTe, a three-dimensional topological insulator. In the absence of a magnetic field , there is no quantizatio…

Tuning confined states and valley g-factors by quantum dot design in bilayer graphene
Dennis Mayer, Angelika Knothe
Electrostatically confined quantum dots in bilayer graphene have shown potential as building blocks for quantum technologies. To operate the dots, e.g., as qubits, a precise unders…

Extended Hubbard model describing small multi-dot arrays in bilayer graphene
Angelika Knothe, Guido Burkard
We set up and parametrize a Hubbard model for interacting quantum dots in bilayer graphene and study double dots as the smallest multi-dot system. We demonstrate the tunability of…
