# Importance of orbital fluctuations for the magnetic dynamics in the heavy-fermion compound SmB6

@article{Singh2018ImportanceOO, title={Importance of orbital fluctuations for the magnetic dynamics in the heavy-fermion compound SmB6}, author={Christopher N. Singh and Wei-Cheng Lee}, journal={Physical Review B}, year={2018} }

The emergent dynamical processes associated with magnetic excitations in heavy-fermion SmB$_6$ are investigated. By imposing multiorbital interactions on a first-principles model, we find the interplay between spin and orbital fluctuations in the $f$ manifold is highly sensitive to local correlations. The magnetic phase diagram constructed at zero temperature reveals quantum critical features with the existence of several competing phases. Within the random phase approximation, we perform a…

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 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.
