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…

Nematic spin correlations pervading the phase diagram of FeSe $_{1 - x}$ S $_{x}$

Ruixian Liu, Wenliang Zhang, Yuan Wei +8

We use resonant inelastic X-ray scattering (RIXS) at the Fe-L $_{3}$ edge to study the spin excitations of uniaxial-strained and unstrained FeSe $_{1 - x}$ S $_{x}$ ( $0 \leq x \leq 0.21$ ) sam…

Evidences for the random singlet phase in a new honeycomb iridate SrIr $_{2}$ O $_{6 - δ}$

Pengbo Song, Kejia Zhu, Fan Yang +13

Strong spin-orbital-coupling magnetic systems with the honeycomb structure can provide bond-directional interactions which may result in Kitaev quantum spin liquids and exotic anyo…

Nonlocal effects of low-energy excitations in quantum-spin-liquid candidate Cu $_{3}$ Zn(OH) $_{6}$ FBr

Yuan Wei, Xiaoyan Ma, Zili Feng +8

We systematically study the low-temperature specific heats for the two-dimensional kagome antiferromagnet, Cu $_{3}$ Zn(OH) $_{6}$ FBr. The specific heat exhibits a $T^{1.7}$ dependence…

Magnetic phase diagram of Cu $_{4 - x}$ Zn $_{x}$ (OH) $_{6}$ FBr studied by neutron-diffraction and $μ$ SR techniques

Yuan Wei, Xiaoyan Ma, Zili Feng +11

We have systematically studied the magnetic properties of Cu $_{4 - x}$ Zn $_{x}$ (OH) $_{6}$ FBr by the neutron diffraction and muon spin rotation and relaxation ( $μ$ SR) techniques. Neutron-d…

Anisotropic spin fluctuations in detwinned FeSe

Tong Chen, Youzhe Chen, Andreas Kreisel +15

Superconductivity in FeSe emerges from a nematic phase that breaks four-fold rotational symmetry in the iron plane. This phase may arise from orbital ordering, spin fluctuations, o…

Antiferromagnetism in kagome $α$ -Cu $_{3}$ Mg(OH) $_{6}$ Br $_{2}$

Yuan Wei, Zili Feng, Clarina dela Cruz +5

The antiferromagnetism in $α$ -Cu $_{3}$ Mg(OH) $_{6}$ Br $_{2}$ was studied by magnetic-susceptibility, specific-heat and neutron-diffraction measurements. The crystal structure consists of C…

Effect of Zn doping on the antiferromagnetism in kagome Cu $_{4 - x}$ Zn $_{x}$ (OH) $_{6}$ FBr

Zili Feng, Yuan Wei, Ran Liu +10

Barlowite Cu $_{4}$ (OH) $_{6}$ FBr shows three-dimensional (3D) long-range antiferromagnetism, which is fully suppressed in Cu $_{3}$ Zn(OH) $_{6}$ FBr with a kagome quantum spin liquid ground st…

Evidence for the topological order in a kagome antiferromagnet

Yuan Wei, Zili Feng, Wiebke Lohstroh +19

A Z2 quantum spin liquid hosts one of the simplest topological orders and exhibits many exotic properties due to long-range quantum entanglements. Its elementary excitations are an…

Gapped spin-1/2 spinon excitations in a new kagome quantum spin liquid compound Cu $_{3}$ Zn(OH) $_{6}$ FBr

Zili Feng, Zheng Li, Xin Meng +14

We report a new kagome quantum spin liquid candidate Cu $_{3}$ Zn(OH) $_{6}$ FBr, which does not experience any phase transition down to 50 mK, more than three orders lower than the antife…
