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…
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…
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}|…
Asymmetric stress engineering of dense dislocations in brittle superconductors for strong vortex pinning
Meng Han, Chiheng Dong, Chao Yao +17
Large lossless currents in high-temperature superconductors (HTS) critically rely on dense defects with suitable size and dimensionality to pin vortices, with dislocations being pa…
The Fermi surface of RuO2 measured by quantum oscillations
Zheyu Wu, Mengmeng Long, Hanyi Chen +12
The metallic oxide RuO has emerged as a promising altermagnet candidate, owing to reports of this material hosting antiferromagnetic ordering accompanied by a spin-split electr…
Observation of quantum oscillations near the Mott-Ioffe-Regel limit in CaAs3
Yuxiang Wang, Minhao Zhao, Jinglei Zhang +24
The Mott-Ioffe-Regel limit sets the lower bound of carrier mean free path for coherent quasiparticle transport. Metallicity beyond this limit is of great interest because it is oft…
Purity-dependent Lorenz number, electron hydrodynamics and electron-phonon coupling in WTe
Wei Xie, Feng Yang, Liangcai Xu +3
We present a study of electrical and thermal transport in Weyl semimetal WTe down to 0.3 K. The Wiedemann-Franz law holds below 2 K and a downward deviation starts above. The d…
