Revealing Intrinsic Anisotropy of Collective Magnetic Excitations in Twinned Crystals of a Kitaev-Heisenberg Quantum Magnet
Naipeng Zhang, Nikolai Simonov, Mykhaylo Ozerov +11
Quantum magnets with competing interactions often emerge from delicate balances among microscopic parameters, making it essential to disentangle intrinsic spin dynamics from extrin…
Spin dynamics of the spin-1 triangular lattice Heisenberg antiferromagnet KNi(SeO)
Chaebin Kim, Sathvik Nallapati, E. A. Ghioldi +6
Strong quantum fluctuations and unconventional spin dynamics are well established in the spin-1/2 triangular lattice Heisenberg antiferromagnet. However, their survival in the spin…
Semiclassical Routes to the -RuCl Scattering Continuum via Model MetaAnalysis
Chaebin Kim, Martin Mourigal
-RuCl is a leading material for proximate Kitaev magnetism. We address the origin of the broad, -point centered excitation continuum observed by inelastic neutron scatt…
Sharp spectroscopic fingerprints of disorder in an incompressible magnetic state
Chaebin Kim, Sumedh Rathi, Naipeng Zhang +15
Disorder significantly impacts the electronic properties of conducting quantum materials by inducing electron localization and thus altering the local density of states and electri…
