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…
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…
Phonon Thermal Hall Effect: The Roles of Disorder, Annealing, and Metallic Contacts
Qiaochao Xiang, Xiaokang Li, Xiaodong Guo +2
The phonon thermal Hall effect (THE) is a ubiquitous yet poorly understood phenomenon in insulators. Its microscopic origin remains debated, partly due to significant sample-depend…
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…
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…
Abnormal planar Hall effect and disentanglement of incoherent and coherent transport in a Kondo lattice
Shuo Zou, Hai Zeng, Zhuo Wang +7
The nature of localized-itinerant transition in Kondo lattice systems remains a mystery despite intensive investigations in past decades. While it is often identified from the cohe…
Angle-dependent planar thermal Hall effect by quasi-ballistic phonons in black phosphorus
Xiaokang Li, Xiaodong Guo, Zengwei Zhu +1
The origin of the phonon thermal Hall effect in insulators is a matter of ongoing debate. The large amplitude of the signal in an elemental non-magnetic solid, such as black phosph…
Onsager reciprocal relation between anomalous transverse coefficients of an anisotropic antiferromagnet
Xiaodong Guo, Xiaokang Li, Zengwei Zhu +1
Whenever two irreversible processes occur simultaneously, time-reversal symmetry of microscopic dynamics gives rise, on a macroscopic level, to Onsager's reciprocal relations, whic…
