Title: Thermal transport in quantum magnets

Abstract: I will present some general results for all components of the thermal conductivity tensor in magnets, especially useful in regimes where the current is not carried by well-defined quasiparticles. This includes, but is not limited to, high temperatures as compared with the magnetic exchange scale, which is most easily accessible in magnets. I will also discuss general results for the effect of phonons coupled to other degrees of freedom on the thermal conductivity, obtained within a hydrodynamic approach, and show specific examples in magnets.
