Signatures of Topological Magnon Edge States in THz Spectroscopy and Cavity Response
Ipsika Mohanty, Johannes Knolle, Silvia Viola Kusminskiy
Topological magnon insulators (TMIs) have emerged as promising platforms for low-energy spin-based information processing, due to their non-trivial bulk magnon topology and robust,…
Interaction-induced crystalline topology of excitons
Henry Davenport, Johannes Knolle, Frank Schindler
We apply the topological theory of symmetry indicators to interaction-induced exciton band structures in centrosymmetric semiconductors. Crucially, we distinguish between the topol…
Genuine topological Anderson insulator from impurity induced chirality reversal
Avedis Neehus, Frank Pollmann, Johannes Knolle
We investigate a model of Dirac fermions with Haldane type mass impurities which open a global topological gap even in the dilute limit. Surprisingly, we find that the chirality of…
Berry curvature-induced local spin polarisation in gated graphene/WTe heterostructures
Lukas Powalla, Jonas Kiemle, Elio J. König +6
Full experimental control of local spin-charge interconversion is of primary interest for spintronics. Heterostructures combining graphene with a strongly spin-orbit coupled two-di…
Robustness of Majorana edge modes and topological order -- exact results for the symmetric interacting Kitaev chain with disorder
Max McGinley, Johannes Knolle, Andreas Nunnenkamp
We investigate the robustness of Majorana edge modes under disorder and interactions. We exploit a recently found mapping of the interacting Kitaev chain in the symmetric region ($…
The Anomalous de Haas-van Alphen Effect in InAs/GaSb quantum wells
Johannes Knolle, Nigel R. Cooper
The de Haas-van Alphen effect (dHvAe) describes the periodic oscillation of the magnetisation in a material as a function of inverse applied magnetic field. It forms the basis of a…
