Modified anisotropy and distinct phase diagrams in the nearly isotropic triangular-lattice antiferromagnet
Xuejuan Gui, Xu-Guang Zhou, Chen Zhang +13
The triangular-lattice antiferromagnet serves as a benchmark platform for realizing exotic quantum phases, in which magnetic anisotropy plays an essential role. In this work, we re…
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…
Spin-supersolidity induced quantum criticality and magnetocaloric effect in the triangular-lattice antiferromagnet RbCo(SeO)
Yi Cui, Zhanlong Wu, Zhongcen Sun +12
We performed high-field magnetization, magnetocaloric effect (MCE), and NMR measurements on the Ising triangular-lattice antiferromagnet RbCo(SeO). The observations of…
Deconfined Quantum Critical Point: A Review of Progress
Yi Cui, Rong Yu, Weiqiang Yu
Deconfined quantum critical points (DQCPs) have been proposed as a class of continuous quantum phase transitions occurring between two ordered phases with distinct symmetry-breakin…
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…
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…
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…
Field-induced phase transitions and quantum criticality in a honeycomb antiferromagnet Na3Co2SbO6
Ze Hu, Yue Chen, Yi Cui +10
We performed 23Na NMR measurements on a single-domain crystal of the Kitaev material Na3Co2SbO6, with magnetic field applied along the crystalline a axis. A positive Curie-Weiss co…
