Hierarchy of exchange interactions in the triangular-lattice spin-liquid YbMgGaO
Xinshu Zhang, Fahad Mahmood, Marcus Daum +7
The spin-1/2 triangular lattice antiferromagnet YbMgGaO has attracted recent attention as a quantum spin-liquid candidate with the possible presence of off-diagonal anisotrop…
Direct observation of the Higgs amplitude mode in a two-dimensional quantum antiferromagnet near the quantum critical point
Tao Hong, Masashige Matsumoto, Yiming Qiu +12
Spontaneous symmetry-breaking quantum phase transitions play an essential role in condensed matter physics. The collective excitations in the broken-symmetry phase near the quantum…
Magnetic Frustration Driven by Itinerancy in Spinel CoV2O4
J. H. Lee, J. Ma, S. E. Hahn +7
Localized spins and itinerant electrons rarely coexist in geometrically-frustrated spinel lattices. We show that the spinel CoV2O4 stands at the crossover from insulating to itiner…
The nature of spin excitations in the one-third magnetization plateau phase of BaCoSbO
Y. Kamiya, L. Ge, Tao Hong +10
Magnetization plateaus in quantum magnets---where bosonic quasiparticles crystallize into emergent spin superlattices---are spectacular yet simple examples of collective quantum ph…
