Unusual violation of the Wiedemann–Franz law at ultralow temperatures in topological compensated semimetals

Abstract Thermal conductivity and electrical resistivity at ultralow temperatures and high magnetic fields are studied in the topological compensated semimetals TaAs2, NbAs2, and NdSb. A striking phenomenon is observed where the thermal conductivity shows a T 4 scaling at very low temperatures, whil...
