Symmetry-enforced double Weyl points, multiband quantum geometry, and singular flat bands of doping-induced states at the Fermi level
Moritz M. Hirschmann, Johannes Mitscherling
Two common difficulties in the design of topological quantum materials are that the desired features lie too far from the Fermi level and are spread over a too-large energy range.…
Non-coplanar helimagnetism in the layered van-der-Waals metal DyTe
Shun Akatsuka, Sebastian Esser, Shun Okumura +10
Magnetic materials with highly anisotropic chemical bonding can be exfoliated to realize ultrathin sheets or interfaces with highly controllable optical or spintronics responses, w…
Correlation Induced Magnetic Topological Phases in Mixed-Valence Compound SmB6
Huimei Liu, Moritz M. Hirschmann, George A. Sawatzky +2
SmB6 is a mixed-valence compound with flat f-electron bands that have a propensity to magnetism. Here, using a realistic Gamma8 quartet model, we investigate the dynamical spin sus…
Fundamental laws of chiral band crossings: local constraints, global constraints, and topological phase diagrams
Kirill Alpin, Moritz M. Hirschmann, Niclas Heinsdorf +4
We derive two fundamental laws of chiral band crossings: (i) a local constraint relating the Chern number to phase jumps of rotation eigenvalues; and (ii) a global constraint deter…
