Disorder-induced spin-cluster magnetism in a doped kagome spin liquid candidate
Arnab Seth, Joseph C. Prestigiacomo, Aini Xu +6
The search for new quantum spin liquid materials relies on systems with strong frustration such as spins on an ideal kagome lattice. However, lattice imperfections can have substan…
Spin excitations arising from anisotropic Dirac spinons in YCu(OD)Br[Br(OD)]
Lankun Han, Zhenyuan Zeng, Min Long +10
A Dirac quantum spin liquid hosts Dirac spinons, which are low-energy fractionalized neutral quasiparticles with spin 1/2 that obey the Dirac equation. Recent inelastic neutron sca…
Unconventional Magnetic Oscillations in Kagome Mott Insulators
Guoxin Zheng, Yuan Zhu, Kuan-Wen Chen +12
In metals, electrons in a magnetic field undergo cyclotron motion, leading to oscillations in physical properties called quantum oscillations. This phenomenon has never been seen i…
Thermodynamic evidence of fermionic behavior in the vicinity of one-ninth plateau in a kagome antiferromagnet
Guoxin Zheng, Dechen Zhang, Yuan Zhu +13
The spin-1/2 kagome Heisenberg antiferromagnets are believed to host exotic quantum entangled states. Recently, the report of 1/9 magnetization plateau and magnetic oscillations in…
Magnetic ground states in kagome YCu(OH)[(ClBr)(OH)]
Aini Xu, Qinxin Shen, Bo Liu +7
Quantum spin liquids represent exotic states of spin systems characterized by long-range entanglement and emergent fractionalized quasiparticles. It is generally believed that diso…
Spectral evidence for Dirac spinons in a kagome lattice antiferromagnet
Zhenyuan Zeng, Chengkang Zhou, Honglin Zhou +10
Emergent quasiparticles with a Dirac dispersion in condensed matter systems can be described by the Dirac equation for relativistic electrons, in analogy with Dirac particles in hi…
