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 hydrodynamic regimes in sapphire

Takuya Kawabata, Kosuke Shimura, Yuto Ishii +7

When an ideal insulator is cooled, four regimes of thermal conductivity are expected to emerge one after another. Two of these, the Ziman and the Poiseuille, are hydrodynamic regim…

Near-critical dark opalescence in out-of-equilibrium SF

Valentina Martelli, Amaury Anquetil, Lin Al Atik +4

The first-order phase transition between the liquid and gaseous phases ends at a critical point. Critical opalescence occurs at this singularity. Discovered in 1822, it is known to…

The phonon thermal Hall angle in black phosphorus

Xiaokang Li, Yo Machida, Alaska Subedi +3

The origin of phonon thermal Hall Effect (THE) observed in a variety of insulators is yet to be identified. Here, we report on the observation of a thermal Hall conductivity in a n…

Mesoscopic tunneling in strontium titanate

Benoît Fauqué, Philippe Bourges, Alaska Subedi +6

Spatial correlation between atoms can generate a depletion in the energy dispersion of acoustic phonons. Two well known examples are rotons in superfluid helium and the Kohn anomal…

Formation of an electron-phonon bi-fluid in bulk antimony

Alexandre Jaoui, Adrien Gourgout, Gabriel Seyfarth +4

The flow of charge and entropy in solids usually depends on collisions decaying quasiparticle momentum. Hydrodynamic corrections can emerge, however, if most collisions among quasi…

Departure from the Wiedemann-Franz Law in WP Driven by Mismatch in -square Resistivity Prefactors

Alexandre Jaoui, Benoît Fauqué, Carl Willem Rischau +8

The Wiedemann-Franz (WF) law establishes a link between heat and charge transport due to electrons in solids. The extent of its validity in presence of inelastic scattering is a qu…

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…
