Three-dimensional spin susceptibility in BaKFeAs: Out-of-plane modulation revealed by neutron spectroscopy and theoretical modeling
Naoki Murai, Katsuhiro Suzuki, Masamichi Nakajima +4
We present a combined experimental and theoretical investigation of the spin dynamics in the iron-based superconductor BaKFeAs. Time-of-flight inelastic n…
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…
Continuum of spin excitations in an ordered magnet
Jieming Sheng, Le Wang, Wenrui Jiang +9
Continuum of spin excitations observed in inelastic neutron scattering experiments are often considered as a strong evidence of quantum spin liquid formation. When quantum spin liq…
The influence of Structural Dynamics in Two-Dimensional Hybrid Organic-Inorganic Perovskites on their Photoluminescence Efficiency -- Neutron scattering analysis
Haritha Sindhu Rajeev, Xiao Hu, Wei-Liang Chen +12
Two-dimensional hybrid organic-inorganic perovskites (HOIPs) have emerged as promising materials for light-emitting diode applications. In this study, by using time-of-flight neutr…
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…
