Field-induced spin level crossings within a quasi-XY antiferromagnetic state in BaFeSiO
Minseong Lee, Rico Schoenemann, Hao Zhang +11
We present a high-field study of the strongly anisotropic easy-plane square lattice = 2 quantum magnet BaFeSiO. This compound is a rare high-spin antiferromag…
Phonons and phase symmetries in bulk from scattering measurements and theory
Xun Li, Seunghwan Do, Jiaqiang Yan +7
Phonon-derived behaviors are important indicators of novel phenomena in transition metal trihalides, including spin liquid behavior, two-dimensional magnetism, and spin-lattice cou…
Understanding temperature-dependent SU() spin dynamics in the antiferromagnet BaFeSiO
Seung-Hwan Do, Hao Zhang, David A. Dahlbom +9
Quantum magnets admit more than one classical limit and -level systems with strong single-ion anisotropy are expected to be described by a classical approximation based on SU($N…
Gaps in Topological Magnon Spectra: Intrinsic vs. Extrinsic Effects
Seung-Hwan Do, Joseph A. M. Paddison, Gabriele Sala +9
For topological magnon spectra, determining and explaining the presence of a gap at a magnon crossing point is a key to characterize the topological properties of the system. An in…
Weak-coupling to strong-coupling quantum criticality crossover in a Kitaev quantum spin liquid -RuCl
Jae-Ho Han, Seung-Hwan Do, Kwang-Yong Choi +5
We report an unprecedented quantum criticality crossover representing two different universal scaling behaviors in a Kitaev quantum magnetic material -RuCl. -RuCl pre…
