Topological and disorder corrections to the transverse Wiedemann-Franz law and Mott relation in kagome magnets and Dirac materials
Topological and disorder corrections to the transverse Wiedemann-Franz law and Mott relation in kagome magnets and Dirac materials
The Wiedemann-Franz law and Mott relation are textbook paradigms on the ratios of the thermal and thermoelectric conductivities to electrical conductivity, respectively. Deviations from them usually reveal insights for intriguing phases of matter. The recent topological kagome magnets $\mathrm{Tb}{\mathrm{Mn}}_{6}{\mathrm{Sn}}_{6}$ and ${\mathrm{Mn}}_{3}\mathrm{Ge}$ show confusingly opposite derivations in the Hall measurement. We …
