Multiband transport hierarchy and large Nernst effect in EuAuBi: Establishing a Nernst scaling for asymmetric multiband systems
Weimin Quan, Xiaodong Guo, Lingxiao Zhao +4
In correlated materials, coexisting pockets of vastly different carrier densities raise two fundamental questions: which pocket governs the various transport coefficients, and does…
Hydrodynamics of the viscous electron fluid in cadmium
Xiaodong Guo, Xiaokang Li, Benoît Fauqué +4
Thanks to electron-electron (-) collisions conserving momentum, metallic electron fluids are viscous. Yet, this viscosity is rarely detectable in bulk transport. Here, we rep…
Scalable Sondheimer oscillations driven by commensurability between two quantizations
Xiaodong Guo, Xiaokang Li, Lingxiao Zhao +2
The electrical conductivity of metallic crystals exhibits size effects when the electron mean free path exceeds the sample thickness. One such phenomenon, known as Sondheimer oscil…
Thermodynamic origin of the phonon Hall effect in a honeycomb antiferromagnet
Qingkai Meng, Xiaokang Li, Jie Liu +5
The underlying mechanism of the thermal Hall effect (THE) generated by phonons in a variety of insulators is yet to be identified. Here, we report on a sizeable thermal Hall conduc…
