Thermal Hall conductivity of $\alpha$-RuCl${}_3$

Abstract

Thermal Hall conductivity originating from topological magnons is observed in the Kitaev candidate $\alpha$-RuCl${}_3$ in broad intervals of temperature and in-plane magnetic field, raising questions on the role of the Majorana mode in heat conduction.
