Electron-phonon coupled hydrodynamics in semimetal TaAs_2
Shan Jiang, Wei Xie, Xiaokang Li +2
Hydrodynamic corrections to diffusive transport can arise when momentum-conserving collisions between quasiparticles become prominent, and they have been documented for both electr…
Pulsed thermal annealing enables switching of chiral antiferromagnetic order with a sub-millitesla field in MnSn
Xiaokang Li, Jing Zhang, Xiaodong Guo +1
The manipulation of antiferromagnetic (AFM) order is a central theme in modern spintronics. In this work, we achieve reliable switching of the chiral AFM state in the Weyl antiferr…
Thermal Hall resistivity and transverse entropy production in a phonon gas
Xiaodong Guo, Xiaokang Li, Alaska Subedi +2
Most theories of the phonon thermal Hall effect ignore phonon-phonon interactions. Here, by recalling the Senftleben-Beenakker effect in molecular gases, we argue that a magnetic f…
Comment on `High-resolution Measurements of Thermal Conductivity Matrix and Search for Thermal Hall Effect in LaCuO'
Shan Jiang, Qiaochao Xiang, Benoît Fauqué +3
Recently, Jiayi Hu and co-workers reported that they did not resolve any thermal Hall signal in LaCuO by `high resolution' measurements, setting an upper bound of $|κ_{xy}|…
Discovery of a large magnetic nonlinear Hall effect in an altermagnet
Lei Han, Xizhi Fu, Cheng Song +10
Since Edwin Halls groundbreaking discovery of the Hall effect in 1879, magnetism, spin, and quantization have been expanding the scope of Hall effects, continuously driving transfo…
Magnetic memory and distinct spin populations in ferromagnetic Co3Sn2S2
Charles Menil, Brigitte Leridon, Antonella Cavanna +7
Co3Sn2S2, a ferromagnetic Weyl semi-metal with Co atoms on a kagome lattice, has generated much recent attention. Experiments have identified a temperature scale below the Curie te…
Glass-like thermal conductivity and narrow insulating gap of EuTiO
Alexandre Jaoui, Shan Jiang, Xiaokang Li +8
Crystals and glasses differ by the amplitude and the temperature dependence of their thermal conductivity. However, there are crystals known to display glass-like thermal conductiv…
Field-linear anomalous Hall effect and Berry curvature induced by spin chirality in the kagome antiferromagnet Mn3Sn
Xiaokang Li, Jahyun Koo, Zengwei Zhu +2
During the past two decades, it has been established that a non-trivial electron wave-function topology generates an anomalous Hall effect (AHE), which shows itself as a Hall condu…
Planar Hall effect caused by the memory of antiferromagnetic domain walls in MnGe
Liangcai Xu, Xiaokang Li, Linchao Ding +2
In MnX (X=Sn, Ge) antiferromagnets domain walls are thick and remarkably complex because of the non-collinear arrangement of spins in each domain. A planar Hall effect (PHE), a…
Eightfold Fermionic Excitation in a Charge Density Wave Compound
Xi Zhang, Qiangqiang Gu, Haigen Sun +19
Unconventional quasiparticle excitations in condensed matter systems have become one of the most important research frontiers. Beyond two- and fourfold degenerate Weyl and Dirac fe…
Intrinsic anomalous Nernst effect amplified by disorder in a half-metallic semimetal
Linchao Ding, Jahyun Koo, Liangcai Xu +9
Intrinsic anomalous Nernst effect (ANE), like its Hall counterpart, is generated by Berry curvature of electrons in solids. Little is known about its response to disorder. In contr…
Momentum-space and real-space Berry curvatures in MnSn
Xiaokang Li, Liangcai Xu, Huakun Zuo +3
MnX (X= Sn, Ge) are noncollinear antiferromagnets hosting a large anomalous Hall effect (AHE). Weyl nodes in the electronic dispersions are believed to cause this AHE, but th…
