Spiral spin liquid resilient to quantization in the frustrated honeycomb antiferromagnet GdZnPO
Xun Chen, Rui Bian, Yuqian Zhao +4
Frustrated magnets host strong quantum fluctuations that can suppress conventional magnetic order and give rise to exotic quantum phases such as spin liquids. In some cases, howeve…
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 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…
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…
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…
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…
