Symmetry-Enforced Nodal -Wave Magnets
Moritz M. Hirschmann, Akira Furusaki, Max Hirschberger
Owing to their relevance for spintronics, electronic band splitting and spin-polarization textures in magnets are active areas of research. In non-collinear magnets, alternating sp…
Spiral-induced Anomalous Hall Effect from Odd-parity Spin-nodal Lines
Shun Okumura, Moritz M. Hirschmann, Yukitoshi Motome
Spin spirals represent a fundamental class of noncollinear yet coplanar magnetic structures that give rise to diverse emergent phenomena reflecting spin chirality. We investigate m…
Quantum geometry and low-frequency optical conductivity of nodal planes
Raymond Wiedmann, Kirill Alpin, Moritz M. Hirschmann +1
Nodal planes, two-dimensional symmetry-enforced band crossings, can carry a topological charge, similar to Weyl points. While the transport properties of Weyl points are well under…
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.…
Intertwined Weyl phases emergent from higher-order topology and unconventional Weyl fermions via crystalline symmetry
W. B. Rui, Zhen Zheng, Moritz M. Hirschmann +3
We discover three-dimensional intertwined Weyl phases, by developing a theory to create topological phases. The theory is based on intertwining existing topological gapped and gapl…
Higher-order Weyl superconductors with anisotropic Weyl-point connectivity
W. B. Rui, Song-Bo Zhang, Moritz M. Hirschmann +3
Weyl superconductors feature Weyl points at zero energy in the three-dimensional (3D) Brillouin zone and arc states that connect the projections of these Weyl points on the surface…
