# Topological Kondo Insulators

@inproceedings{Dzero2009TopologicalKI, title={Topological Kondo Insulators}, author={Maxim Dzero and Kai Sun and Victor Galitski and Piers Coleman}, year={2009} }

Kondo insulators are particularly simple type of heavy elec tron material, where a filled band of heavy quasiparticles gives rise to a narrow band insulator. Starting wi th the Anderson lattice Hamiltonian, we develop a topological classification of emergent band structures fo r Kondo insulators and show that these materials may host three-dimensional topological insulating phases . We propose a general and practical prescription of calculating theZ2 strong and weak topological insulator… Expand
