Dynamics of current-induced switching in the quantum anomalous Hall effect
Alina Rupp, Daniel Rosenbach, Torsten Röper +4
Ferromagnetic topological insulators in the quantum anomalous Hall (QAH) regime host chiral, dissipationless edge states whose propagation direction is determined by the internal m…
Breakdown of the quantum anomalous Hall effect under microwave drives
Torsten Röper, Daniel Rosenbach, Achim Rosch +3
Quantum anomalous Hall (QAH) insulators exhibit chiral dissipationless edge states without an external magnetic field, making them a promising material for quantum metrology and mi…
Non-Majorana-origin of the half-integer conductance quantization elucidated by multi-terminal superconductor-quantum anomalous Hall insulator heterostructure
Anjana Uday, Gertjan Lippertz, Bibek Bhujel +2
Chiral one-dimensional transport can be realized in thin films of a surface-insulating ferromagnetic topological insulator called quantum anomalous Hall insulator (QAHI). When supe…
Characterizing the chemical potential disorder in the topological insulator (BiSb)Te thin films
Jens Brede, Mahasweta Bagchi, Adrian Greichgauer +6
We use scanning tunneling microscopy and spectroscopy under ultra-high vacuum and down to 1.7 K to study the local variations of the chemical potential on the surface of the topolo…
Propagation, dissipation and breakdown in quantum anomalous Hall edge states probed by microwave edge plasmons
Torsten Röper, Hugo Thomas, Daniel Rosenbach +7
The quantum anomalous Hall (QAH) effect, with its single chiral, topologically protected edge state, offers a platform for flying Majorana states as well as non-reciprocal microwav…
Induced superconducting correlations in the quantum anomalous Hall insulator
Anjana Uday, Gertjan Lippertz, Kristof Moors +5
Inducing Cooper pairing in a thin ferromagnetic topological insulator in the quantum anomalous Hall state (called quantum anomalous Hall insulator, QAHI) is a promising way to real…
