Kavli Affiliate: James Analytis| Summary:Standard bulk probes of multiband superconductors cannot assign pairing gaps to specific electron or hole Fermi surfaces. Here we show that thermal Hall transport ($κ_xy$), constrained by specific heat and normal-state magnetotransport, resolves this ambiguity in the compensated heavy-fermion superconductor CeRu$_2$. Fixing the gap magnitudes ($Δ_e/k_Bapprox 13$K, $Δ_h/k_Bapprox 8$K) and band […]
