Strongly Correlation and Topology in Kondo Lattice Systems

Quantum materials with both strong correlations and nontrivial band structure topology can have novel physics properties that do not exist in the non-correlated counterparts. Recent theoretical work has demonstrated that combination of Kondo physics and nonsymmorphic crystal symmetries can give rise to such strong correlated topological systems.

In this talk, I will present our recent experimental exploration this direction. In one case, we found intrinsic anomalous Hall effect that seems to break the Fermi liquid scaling relation. In another case, we have discovered a candidate for topological Kondo insulator.
