Optical phonons as a testing ground for spin group symmetries
F. Schilberth, M. Kondákor, D. Ukolov +12
Lattice vibrations are highly sensitive to crystal symmetries and their changes across phase transitions. The latter can modify irreducible (co)representations and corresponding in…

Generation of Weyl points and a nodal line by magnetization reorientation in CoSnS
F. Schilberth, M. -C. Jiang, F. Le Mardelé +11
Topological magnets exhibit fascinating properties like topologically protected surface states or anomalous transport phenomena. While these properties can be significantly altered…

Large magnetoreflectance and optical anisotropy due to flat bands in the frustrated kagome magnet HoAgGe
F. Schilberth, L. DeFreitas, K. Zhao +7
We report peculiar optical properties of the frustrated itinerant magnet HoAgGe, which exhibits multiple magnetically ordered states obeying the kagome spin-ice rule. The optical c…
