Coherent high-velocity chiral magnons in the metallic altermagnet CrSb
Ashutosh K. Singh, Niclas Heinsdorf, Abraham A. Mancilla +8
We report the collective magnetism of the metallic altermagnet CrSb. Magnetic susceptibility and polarized neutron diffraction measurements show that CrSb is a perfectly compensate…
Intrinsic defect intolerance in the ultra-pure metal PtSn
Samikshya Sahu, Dong Chen, Niclas Heinsdorf +6
Ultra-pure materials are highly valued as model systems for the study of intrinsic physics. Frequently, however, the crystal growth of such pristine samples requires significant op…
Gapped nodal planes drive a large topological Nernst effect in a chiral lattice antiferromagnet
N. D. Khanh, S. Minami, M. Hirschmann +15
The electronic structure of compensated antiferromagnets (CAF) has drawn attention for its ability to create large responses, reminiscent of ferromagnets and suitable for data stor…
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…
Symmetry-enforced topological band crossings in orthorhombic crystals: Classification and materials discovery
Andreas Leonhardt, Moritz M. Hirschmann, Niclas Heinsdorf +3
We identify all symmetry-enforced band crossings in nonmagnetic orthorhombic crystals with and without spin-orbit coupling and discuss their topological properties. We find that or…
A semimetallic square-octagon (fes) two-dimensional polymer with high mobility
Tsai-Jung Liu, Maximilian A. Springer, Niclas Heinsdorf +3
The electronic properties of -conjugated two-dimensional (2D) polymers near the Fermi level are determined by structural topology and chemical composition. Thus, tight-binding (…
