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…
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…
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…
