Quantum Fisher Information in semiclassical magnon systems
Wolfgang Simeth, Pontus Laurell, Allen Scheie
Quantum Fisher Information (QFI) is a powerful spectroscopic tool to witness many-body quantum entanglement in solid state materials, but it is not always obvious how to relate it…
Magnetic devil's staircase in UAgBi
G. S. Freitas, K. Kirchner, C. Girod +10
Materials characterized by competing interactions often exhibit a large number of nearly degenerate periodic states. Here we show that layered UAgBi hosts a cascade of field- a…
Magnetic symmetry implications of the zero- and applied-field Hall effect of UNiB
Z. W. Riedel, W. S. Simeth, S. M. Thomas +2
The zero-field and applied-field Hall effects in noncollinear antiferromagnets provide evidence for topological states of matter and are tied to materials' magnetic symmetry. For U…
Magnetic order, magnons, and crystal fields in van der Waals CeSiI
Wolfgang Simeth, Connor A. Occhialini, Michael E. Ziebel +12
We report neutron, X-ray absorption, and resonant X-ray spectroscopy of magnetic excitations in the new heavy-fermion van-der-Waals superconductor CeSiI. We determined effective Ha…
Enhanced two-dimensional ferromagnetism in van der Waals -UTe monolayers
S. M. Thomas, A. E. Llacsahuanga, W. Simeth +11
The discovery of local-moment magnetism in van der Waals (vdW) semiconductors down to the single-layer limit has led to a paradigm shift in the understanding of two-dimensional (2D…
