  • The thermal Hall effect is a novel probe of neutral excitations in insulators; however, the mechanism behind one type of neutral excitations – phonons – is still unclear. Here the authors observe a planar thermal Hall effect in the Kitaev candidate material Na2Co2TeO6 and proposed that it is generated by phonons.

  • What makes the phonons in cuprates become chiral, as measured by their thermal Hall effect, is an unresolved question. Here, the authors rule out two extrinsic mechanisms and argue that chirality comes from a coupling of acoustic phonons to the intrinsic excitations of the CuO2 planes.
