Itinerant and topological excitations in a honeycomb spiral spin liquid candidate
Yuqian Zhao, Xuping Yao, Xun Chen +4
The frustrated insulating magnet can stabilize a spiral spin liquid, arising from cooperative fluctuations among a subextensively degenerate manifold of spiral configurations, with…
Giant Magnetocaloric Effect in a Honeycomb Spiral Spin-Liquid Candidate
Yuqian Zhao, Xun Chen, Zongtang Wan +2
Unlike conventional magnetic states, which lack degeneracy, the spiral spin liquid (SSL) fluctuates among degenerate spiral configurations, with ground-state wave vectors forming a…
Spiral spin liquid in a frustrated honeycomb antiferromagnet: A single-crystal study of GdZnPO
Zongtang Wan, Yuqian Zhao, Xun Chen +4
The frustrated honeycomb spin model can stabilize a subextensively degenerate spiral spin liquid with nontrivial topological excitations and defects, but its material realization r…
Quantum annealing of a frustrated magnet
Yuqian Zhao, Zhaohua Ma, Zhangzhen He +4
Quantum annealing, which involves quantum tunnelling among possible solutions, has state-of-the-art applications not only in quickly finding the lowest-energy configuration of a co…
Proximate Tomonaga-Luttinger liquid in a spin-1/2 ferromagnetic XXZ chain compound
Boqiang Li, Xun Chen, Yuqian Zhao +3
The spin-1/2 ferromagnetic XXZ chain is a prototypical many-body quantum model, exactly solvable via the integrable Bethe ansatz method, hosting a Tomonaga-Luttinger spin liquid. H…
