Bulk-boundary-defect correspondence at disclinations in rotation-symmetric topological insulators and superconductors
Max Geier, Ion Cosma Fulga, Alexander Lau
We study a link between the ground-state topology and the topology of the lattice via the presence of anomalous states at disclinations -- topological lattice defects that violate…
Coherent Electron Optics with Ballistically Coupled Quantum Point Contacts
Jaan Freudenfeld, Max Geier, Vladimir Umansky +2
The realization of integrated quantum circuits requires precise on-chip control of charge carriers. Aiming at the coherent coupling of distant nanostructures at zero magnetic field…
Electrostatic potential shape of gate defined quantum point contacts
Max Geier, Jaan Freudenfeld, Jorge T. Silva +5
Quantum point contacts (QPC) are fundamental building blocks of nanoelectronic circuits. For their emission dynamics as well as for interaction effects such as the 0.7-anomaly the…
