Enhanced low-energy magnetic excitations evidencing the Cu-induced localization in an Fe-based superconductor FeTeSe
Jinghui Wang, Song Bao, Yanyan Shangguan +11
We have performed inelastic neutron scattering measurements on optimally-doped FeTeSe and 10% Cu-doped FeCuTeSe to investi…
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…
Topological magnon insulator spin excitations in the two-dimensional ferromagnet CrBr
Zhengwei Cai, Song Bao, Zhao-Long Gu +17
Topological magnons are bosonic analogues of topological fermions in electronic systems. They have been studied extensively by theory but rarely realized by experiment. Here, by pe…
Disorder-induced spin-liquid-like behavior in kagome-lattice compounds
Zhen Ma, Zhao-Yang Dong, Si Wu +14
Quantum spin liquids (QSLs) are an exotic state of matter that is subject to extensive research. However, the relationship between the ubiquitous disorder and the QSL behaviors is…
Evidence for magnon-phonon coupling in the topological magnet CuTeO
Song Bao, Zhengwei Cai, Wenda Si +11
We perform thermodynamic and inelastic neutron scattering (INS) measurements to study the lattice dynamics (phonons) of a cubic collinear antiferromagnet CuTeO which hosts…
Spin dynamics of a magnetic Weyl semimetal SrMnSb
Zhengwei Cai, Song Bao, Wei Wang +12
Dirac matters provide a platform for exploring the interplay of their carriers with other quantum phenomena. SrMnSb has been proposed to be a magnetic Weyl semi…
Evidence for singular-phonon-induced nematic superconductivity in a topological superconductor candidate SrBiSe
Jinghui Wang, Kejing Ran, Shichao Li +11
Superconductivity mediated by phonons is typically conventional, exhibiting a momentum-independent s-wave pairing function, due to the isotropic interactions between electrons and…
Recent progress on magnetic-field studies on quantum-spin-liquid candidates
Zhen Ma, Kejing Ran, Jinghui Wang +4
Quantum spin liquids (QSLs) represent a novel state of matter in which quantum fluctuations prevent conventional magnetic order from being established, and the spins remain disorde…
Unusual phonon density of states and response to the superconducting transition in the In-doped topological crystalline insulator PbSnTe
Kejing Ran, Ruidan Zhong, Tong Chen +13
We present inelastic neutron scattering results of phonons in (PbSn)InTe powders, with and 0.3. The sample is a topological crystalline insu…
Evidence for a Dirac nodal-line semimetal in SrAs
Shichao Li, Zhaopeng Guo, Dongzhi Fu +11
Dirac nodal-line semimetals with the linear bands crossing along a line or loop, represent a new topological state of matter. Here, by carrying out magnetotransport measurements an…
Discovery of coexisting Dirac and triply degenerate magnons in a three-dimensional antiferromagnet
Song Bao, Jinghui Wang, Wei Wang +11
Topological magnons are emergent quantum spin excitations featured by magnon bands crossing linearly at the points dubbed nodes, analogous to fermions in topological electronic sys…
