Cascade of Spin Liquids in a Bilayer Triangular-lattice Antiferromagnet Rb_2Co_2(SeO_3)_3
Xiaoyu Xu, Yunlong Wang, Xuejuan Gui +20
In frustrated Ising magnets, classical spin liquids (CSLs) with macroscopic ground-state degeneracy can survive against conventional magnetic order, as exemplified by systems on tr…
Spinons, solitons and random singlets in the spin-chain compound copper benzoate
Ying Chen, Guijing Duan, Yuejiu Zhao +15
The antiferromagnetic Heisenberg chain is a paradigmatic quantum system hosting exotic excitations such as spinons and solitons, and forming random singlet state in the pre…
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…
NMR study of supersolid phases in the triangular-lattice antiferromagnet Na2BaCo(PO4)2
Xiaoyu Xu, Zhanlong Wu, Ying Chen +10
We report ultra-low-temperature Na NMR measurements on the Ising triangular lattice antiferromagnet NaBaCo(PO), which precisely resolve the phase diagram under m…
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…
