Density-wave order enhances the phonon thermal Hall effect in a trilayer nickelate
Qiaochao Xiang, Enkang Zhang, Xiaokang Li +6
Ruddlesden--Popper nickelates have emerged as a promising platform for high-temperature superconductivity, yet the role of lattice degrees of freedom in their correlated normal sta…
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…
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…
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…
Interaction driven transverse thermal resistivity in a phonon gas
Xiaodong Guo, Xiaokang Li, Alaska Subedi +2
The amplitude of the Hall response of electrons can be understood without invoking interactions. Most theories of the phonon thermal Hall effect have likewise opted for a non-inter…
Thermal Hall conductivity of semimetallic graphite dominated by ambipolar phonon drag
Qiaochao Xiang, Xiaokang Li, Xiaodong Guo +2
It is now known that in addition to electrons, other quasi-particles such as phonons and magnons can also generate a thermal Hall signal. Graphite is a semimetal with extremely mob…
