I will discuss how, in this paper, the authors observe an unusual temperature dependence of the anomalous Hall effect in USbTe. Combining their transport data with ARPES measurements and DMFT calculations, they argue that the Berry curvature causing the anomalous Hall effect originates from the flat bands created by Kondo hybridization at low temperature, suggesting that USbTe is likely a Weyl-Kondo semimetal. I will attempt to place this paper in the context of both theoretical and experimental studies of Weyl-Kondo semimetals, a relatively recently predicted material system that combines strong correlations and topology
