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…
