As an exemplary Kondo insulator, SmB6 has been studied for several decades. However, direct evidence for the development of the Kondo coherent state and for the evolution of the electronic structure in the material has not been obtained due to the compound’s rather complicated electronic and thermal transport behavior. Recently, these open questions have attracted increasing attention as the emergence of a time-reversal-invariant topological surface state in the Kondo insulator has been…

Surface electronic structure of the topological Kondo-insulator candidate correlated electron system SmB6.

The authors' observed in-gap Fermi surface oddness tied with the Kramers' point topology, their coexistence with the two-dimensional transport anomaly in the Kondo hybridization regime, as well as their robustness against thermal recycling, collectively provide strong evidence for protected surface metallicity with a Fermani surface whose topology is consistent with the theoretically predicted topological FermI surface.

Observation of possible topological in-gap surface states in the Kondo insulator SmB6 by photoemission

By performing angle-resolved photoemission spectroscopy experiments, several dispersive states within the hybridization gap of SmB6 show negligible kz dependence, which indicates their surface origin, and photoemissions circular dichroism experiments suggest that the in-gap states possess chirality of the orbital angular momentum.

Direct observation of the spin texture in SmB6 as evidence of the topological Kondo insulator.

These results provide strong evidence that SmB6 can host topological surface states in a bulk insulating gap stemming from the Kondo effect, which can serve as an ideal platform for investigating of the interplay between novel topological quantum states with emergent effects and competing orders induced by strongly correlated electrons.

The Gutzwiller method is used to find that an intragap bound state exists in the heavy Fermi liquid regime and derive a new dI/dV formulation, which includes explicitly the renormalization effect due to the f-electron correlation.

It is found that, as the temperature is lowered, partial screening of the f electrons’ spins gives rise to a spatially modulated Kondo–Fano resonance that is maximal between the surface U atoms, suggesting that the two phenomena involve the same electronic states.

The URu2Si2 ‘hidden order’ state emerges directly from the Fano lattice electronic structure and exhibits characteristics, not of a conventional density wave, but of sudden alterations in both the hybridization at each U atom and the associated heavy fermion states.
