Haldane phase, field-induced magnetic ordering and Tomonaga-Luttinger liquid behavior in a spin-one chain compound NiCO2NH
Shuo Li, Zhanlong Wu, Yanhong Wang +12
We performed single-crystal magnetic susceptibility and H NMR measurements on a quasi-1D, spin-1 antiferromagnet NiCO2NH, with temperature down to 100 mK and…
Two Plaquette-Singlet Phases and Emergent SO(5) Deconfined Quantum Criticality in SrCu2(BO3)2
Yi Cui, Kefan Du, Zhanlong Wu +15
The deconfined quantum critical point (DQCP) has become a central open concept in the physics of quantum matter, and its proposed presence in the Shastry-Sutherland model was follo…
Spin excitations of the Shastry-Sutherland model -- altermagnetism and deconfined quantum criticality
Hongyu Chen, Guijing Duan, Changle Liu +4
Frustrated quantum magnets can host a variety of exotic spin excitations, including fractionalized spin excitations coupled to emergent gauge fields at deconfined quantum critical…
Low-energy spin dynamics in a Kitaev material Na3Ni2BiO6 investigated by NMR
Xinyu Shi, Yi Cui, Yanyan Shangguan +11
We performed 23Na NMR and magnetization measurements on an S = 1, quasi-2D honeycomb lattice antiferromagnet Na3Ni2BiO6. A large positive Curie-Weiss constant of 22.9 K is observed…
NMR evidence of spinon localization in kagome antiferromagnet YCu(OH)Br[Br(OH)]
Shuo Li, Yi Cui, Zhenyuan Zeng +9
We performed nuclear magnetic resonance studies on a kagome antiferromagnet YCu(OH)Br[Br(OH)]. No significant NMR spectral broadening is found in the Br c…
Semiclassical approach to spin dynamics of a ferromagnetic S=1 chain
Chengchen Li, Yi Cui, Weiqiang Yu +1
Motivated by recent experimental progress in the quasi-one-dimensional quantum magnet NiNbO, we study the spin dynamics of an S=1 ferromagnetic Heisenberg chain with single…
