Spin dynamics and continuum spectra of the honeycomb J1-J2 antiferromagnetic Heisenberg model
Cheng Gu, Shun-Li Yu, Jian-Xin Li
We employ the spin cluster perturbation theory to investigate the dynamical properties of the antiferromagnetic - Heisenberg model on the honeycomb lattice. We obtain…
Neutron spectroscopy evidence for a possible magnetic-field-induced gapless quantum-spin-liquid phase in a Kitaev material -RuCl
Xiaoxue Zhao, Kejing Ran, Jinghui Wang +15
As one of the most promising Kitaev quantum-spin-liquid (QSL) candidates, -RuCl has received a great amount of attention. However, its ground state exhibits a long-range zig…
Evidence for strong correlations at finite temperatures in the dimerized magnet NaCuTeO
Yanyan Shangguan, Song Bao, Zhao-Yang Dong +12
Dimerized magnets forming alternating Heisenberg chains exhibit quantum coherence and entanglement and thus can find potential applications in quantum information and computation.…
Disorder-induced broadening of the spin waves in a triangular-lattice quantum-spin-liquid candidate YbZnGaO
Zhen Ma, Zhao-Yang Dong, Jinghui Wang +15
Disorder is important in the study of quantum spin liquids, but its role on the spin dynamics remains elusive. Here, we explore the disorder effect by investigating the magnetic-fi…
Neutron spectroscopy evidence on the dual nature of magnetic excitations in a van der Waals metallic ferromagnet FeGeTe
Song Bao, Wei Wang, Yanyan Shangguan +12
In the local or itinerant extreme, magnetic excitations can be described by the Heisenberg model which treats electron spins as localized moments, or by the itinerant-electron mode…
Electronic structure and spin-lattice relaxation in superconducting vortex states on the kagome lattice near van Hove filling
Hong-Min Jiang, Shun-Li Yu, Xiao-Yin Pan
Starting from a tight-binding model on the kagome lattice near the van Hove filling, the superconducting (SC) properties are investigated self-consistently using the Bogoliubov-de…
